SMM Tier 1 is an authoritative certification system defined by SMM as an independent third-party market research institution for the global new energy industry.

On April 23, at the CCIE-2025SMM (20th) Copper Industry Conference and Copper Industry Expo - Main Forum, hosted by SMM Information & Technology Co., Ltd., SMM Metal Trading Center, and Shandong Aisi Information Technology Co., Ltd., with Jiangxi Copper Corporation and Yingtan Land Port Holding Co., Ltd. as main sponsors, and Shandong Humon Smelting Co., Ltd. as a special co-organizer, Xinhuang Group and Zhongtiao Mountain Nonferrous Metals Group Co., Ltd. as co-organizers, Wang Jianlong, Deputy Director of Metallurgy Department One of China ENFI Engineering & Technology Co., Ltd., shared insights on the global copper smelting landscape and intelligent development. Ben Knoefler, Chairman of the Board of KCI Group, analyzed the global copper market for 2025. 1 Global Copper Resource Distribution Overall, the world's copper resources are relatively abundant, with an estimated 31 billion tons of land-based copper resources and 7 billion tons in deep-sea nodules. Natural copper minerals include native copper, oxides, and sulfides. The world's proven copper reserves are about 10 billion tons, and based on current mine production, the static assurance period for mining is approximately 45 years. In terms of regional distribution, the main areas with concentrated copper ore resources globally are: (1) The western foothills of the Andes in Peru and Chile, South America; (2) The Cordillera region in the western part of the North American continent, mainly in the US and Mexico; (3) Central Africa, particularly in the DRC and Zambia; (4) Central Asia, mainly Kazakhstan, Mongolia, and Russia; (5) Australia. The top five countries in terms of copper ore reserves are Chile, Peru, Australia, Russia, and the DRC, accounting for about 57% of the total. 2 Global Refined Copper Consumption Global copper consumption is mainly concentrated in two types of countries or regions. One type is traditional developed Western countries, where copper consumption is relatively stable. The other type is developing countries and regions experiencing rapid economic growth, which have higher copper consumption growth rates and are key factors in global copper consumption growth. According to ICSG statistics, global refined copper consumption in 2024 was 28.577 million mt, up 5.79% YoY. The growth in global refined copper consumption is mainly supported by strong apparent demand in China. The main areas of global copper consumption are power grids, construction, consumer goods, transportation, and engineering machinery, accounting for 28%, 27%, 22%, 12%, and 11% respectively. As a basic raw material, changes in copper consumption are closely related to global economic development. In recent years, consumption of copper plate/sheet and strip in traditional fields and copper foil for circuit boards has been relatively weak, while copper use in the power and new energy sectors has performed well. 3 Global Refined Copper Production and Capacity Distribution Global refined copper production in 2024 was 28.0228 million mt, up 4.07% YoY. The increase in refined copper production is mainly due to capacity expansion in China and the DRC, while production in other regions decreased by about 1%. As the largest consumer and producer of refined copper, China does not have a significant advantage in copper ore resources and needs to import large amounts of copper concentrates. China's refined copper production and copper concentrate imports In 2024, China's refined copper production was 13.644 million mt, and copper concentrate imports were 28.11 million mt. To address the current state of the copper smelting industry, relevant national departments are promoting the healthy and orderly development of the copper smelting industry through industrial policies, environmental protection policies, and other measures. In general, on the supply side, efforts are being made to deepen supply-side structural reforms, strictly control the disorderly expansion of copper smelting capacity, and accelerate intelligent and green transformation. On the demand side, enterprises are being guided to accelerate technological progress, overcome the shortcomings of copper-based new materials, and fully tap the potential applications of copper in new infrastructure and construction projects. Major Chinese Copper Smelters According to incomplete statistics, there are more than 40 copper smelters (production lines) nationwide, with four groups having a capacity of over 1 million mt/a. 4 Global Copper Smelting Processes and Their Development Copper Smelting Processes Pyrometallurgy (80%): Impurities are removed as slag at high temperatures, resulting in copper anode, which is then electrolyzed to produce refined copper. Traditional matte smelting, the main process for copper smelting, is suitable for sulfide ores. One-step copper smelting, with limited industrial application, is suitable for sulfide ores under special raw material conditions. Hydrometallurgy (20%): Copper is enriched in solution through leaching and extraction processes, followed by electrodeposition to produce refined copper. • Leach-extraction-electrodeposition, suitable for oxide ores, especially for large-scale processing of low-grade oxide ores. • Roast-leach-extraction-electrodeposition, suitable for sulfide ores, mixed ores, and copper-cobalt ores. • Oxygen pressure leach-extraction-electrodeposition, suitable for sulfide ores, mixed ores, and copper-cobalt ores. Copper Pyrometallurgical Process Flow It also elaborated on the hydrometallurgical process flow of copper, including roasting, leaching, extraction, and electrodeposition. Several Main Matte Smelting Processes and Their Development ► Flash Smelting: Flash smelting technology includes Outokumpu flash smelting and INCO flash smelting, with Outokumpu technology being widely applied. China began introducing flash smelting technology in the 1980s. Xiangguang Copper innovated boldly based on flash smelting technology, inventing the vortex flash smelting technology, which received a national invention patent. Advantages include high capacity, high automation, and longer furnace life; disadvantages include high investment, complex feed preparation system, poor adaptability to high-impurity raw materials, and the need to reduce costs through scale effects. Recent developments include: high oxygen (even pure oxygen) smelting, further expansion of single-furnace capacity (500,000 mt/a), continuous innovation and improvement of process equipment, and gradual localization. ► Top-Blown Smelting: Top-blown smelting technology, including Ausmelt smelting and ISA smelting, was introduced to China in the 1990s. Characteristics of top-blown smelting technology include using a submerged lance to blow air and oxygen into the melt pool, providing strong stirring and good reaction kinetics, and high production efficiency. Disadvantages include the need to add fuel, inability to separate slag and copper in the furnace, requiring a settling electric furnace, high comprehensive energy consumption, low utilization of oxygen and fuel, and short furnace life. Recent developments include: increasing oxygen concentration, improving matte grade, raising smelting temperature, and continuously extending lance and furnace life. ► Bottom-Blown Smelting: Bottom-blown smelting is a new copper smelting technology with independent intellectual property rights from China ENFI. It was first industrially applied in Vietnam in 2002, and the first bottom-blown copper smelting production line in China was put into operation in 2008. Advantages include simple feed preparation, low furnace investment, high oxygen utilization, and strong adaptability to raw materials, capable of handling high-impurity raw materials. Disadvantages include high copper content in slag and low direct recovery rate. Developments include: further expansion of single-furnace processing capacity (1.8 million mt/a of concentrate); as a representative technology for matte gold capture, it has low requirements for copper content in concentrate and has been applied in complex gold concentrate processing at Shandong Humon, Central China Gold, and Guotou Jincheng. Zhongjin Lingnan Copper Co., Ltd. (formerly Dongying Fangyuan) developed the "Zhongjin Method" for two-step copper smelting based on bottom-blown smelting. China ENFI and Baotou Huading Copper Industry developed the full bottom-blow three-furnace process based on bottom-blown smelting and continuous bottom-blowing. ► Side-Blown Smelting: Based on Vanyukov smelting technology, China developed and applied oxygen-enriched double side-blowing smelting technology in 2009, which has rapidly developed in recent years. Characteristics of side-blown smelting technology include blowing air and oxygen into the melt pool through tuyeres on both sides of the furnace, improving mass and heat transfer conditions, with low blowing pressure, low copper content in slag, and relatively simple operation. Disadvantages include the need for manual opening and plugging of tuyeres and the need to add coal (mainly to inhibit magnetic iron in slag). Recent developments: Rapidly achieved a leap from 100,000 mt capacity to 400,000 mt capacity, with the maximum bed area reaching 70 square meters. ► P-S Converter Blowing: P-S converter blowing, invented in 1905, has been used for over a century and remains the primary copper matte blowing technology worldwide. Advantages include flexible operation and the ability to balance various cold copper-containing materials and externally purchased cold copper using reaction heat. Disadvantages include periodic intermittent operation, large fluctuations in flue gas volume and sulfur content, which are unfavorable for acid-making systems, large flue gas collection volumes, and difficult-to-solve low-altitude SO2 pollution caused by ladle lifting. The drawbacks of P-S converters have prompted metallurgists to seek continuous blowing technologies. ► Flash Blowing: The world's first flash blowing furnace was commissioned at Kennecott Utah Copper in 1995, forming the "double flash" process when paired with flash smelting. Xiangguang Copper was the first in China to introduce "double flash" technology, and the first flash blowing furnace in China was put into operation in 2007. After years of improvement, it developed into vortex flash blowing technology. Currently, there are six flash blowing furnaces in operation in China, five of which are paired with flash smelting, each with a capacity of over 400,000 mt/a, and one paired with bottom-blown smelting, with a capacity of 300,000-400,000 mt/a. Advantages include easy measurement of solid matte, high automation, and high operating rate. Disadvantages include the need for additional grinding equipment for matte and limitations in handling cold materials like anode stubs due to furnace structure and thermal balance. The maximum single-unit designed capacity has reached 500,000 mt/a. Additionally, it provided a detailed introduction to the processes and developments of bottom-blowing and multi-lance top-blowing. 5 Trends in the Copper Smelting Industry Main factors and trends driving global copper smelting development It also reviewed the development policies of China's copper smelting industry and shared interpretations of the main contents of the High-Quality Development Plan for the Copper Industry (2025-2027). 6 Intelligent Development in the Copper Smelting Industry Background of intelligent transformation and upgrading Policy promotion for intelligent transformation and upgrading In March 2021, the State-owned Assets Supervision and Administration Commission (SASAC) issued the Notice on Accelerating the Digital Transformation of State-Owned Enterprises. In November 2021, the MIIT issued the 14th Five-Year Plan for Deep Integration of Informatization and Industrialization. In April 2020, the MIIT, NDRC, and Ministry of Natural Resources jointly released the Guidelines for the Construction of Smart Factories (Mines) in the Nonferrous Metals Industry (Trial). Among these, the Guidelines for the Construction of Smart Smelting Factories in the Nonferrous Metals Industry, led by China ENFI, provide a top-level design for the intelligent development of the nonferrous metal smelting industry. Overall implementation plan for smart factories Expected effects of smart factory implementation It discussed in detail aspects such as organizational management model reconstruction, innovative digital transformation panoramic view, data assetization, and improvement of technical and economic indicators.

Recently, Chifeng Yuntong Copper Industry Co., Ltd. broke through the bottleneck in the recycling and utilization of high-salinity wastewater and successfully passed the review by an expert panel consisting of seven experts from Changsha Engineering & Research Institute for Nonferrous Metallurgy Co., Ltd. The experts unanimously agreed that the comprehensive treatment project of waste heat and exhaust steam reuse coupled with zero-discharge of high-salinity wastewater at Chifeng Yuntong Copper Industry Co., Ltd. features advanced technology and is the first of its kind in China. As early as the beginning of 2021, the Party Committee of Chifeng Yuntong Copper Industry Co., Ltd. actively responded to the national environmental protection requirements, and made early arrangements for the treatment of high-salinity wastewater. It entrusted the research task of high-salinity wastewater disposal from the tertiary water of acid production and the concentrated chemical water produced from urban reclaimed water to the Power Plant of Chifeng Yuntong Copper Industry Co., Ltd. The Power Plant took swift action and embarked on the journey of exploring the recycling and utilization of high-salinity wastewater. The Party branch of the Power Plant of Chifeng Yuntong Copper Industry Co., Ltd. leveraged its political and organizational functions, and assembled a capable project team by selecting professional technical personnel. Party members in the branch were bold in their assumptions, diligent in their research and experiments. The project team built experimental equipment in-house and conducted a series of process experiments. Throughout the practical process, the team continuously identified, analyzed, and resolved challenges. Through trial and error, they accurately determined the heat source for the recycling and utilization process, providing a clear direction for the project's experiments. To further optimize the process, after screening information from multiple sources, Chifeng Yuntong Copper Industry Co., Ltd. ultimately reached a cooperation agreement with China ENFI Engineering Corporation. Leveraging its patented LTE low-temperature thermal concentration technology, the company conducted experiments on the low-temperature evaporation and concentration stage of high-salinity wastewater. The experimental results were remarkable, achieving a target water production rate of 90%, with an average conductivity of the produced water of only 66.18 μs/cm. The produced water can be directly used as makeup water for circulating water, among other applications. The project team focused on investigating the corrosion conditions on the surface of coupons made of different materials during the wastewater concentration process, identifying the core materials, and providing a crucial basis for equipment material selection. Building on the previous work, the project team explored and implemented an innovative low-temperature evaporation and concentration coupled with an air omnipotent tower to revolutionize the low-temperature evaporation crystallization and salt separation process. This successfully produced qualified sodium sulphate anhydrous (meeting the Class II qualified product standard of GB/T 6009-2014, "Industrial Anhydrous Sodium Sulphate") and sodium chloride (meeting the solar salt standard for industrial salt in GB/T 5462-2015, "Industrial Salt"). This innovation not only significantly reduced equipment energy consumption and operating costs but also opened up a new path for high-salinity wastewater treatment. The project team continued to focus on ion control and the optimization of the operating cycle, precisely controlling the content of calcium ions, fluoride ions, chloride ions, and other ions in high-salinity wastewater, and gradually clarifying the influence of ion changes on scaling and the issue of titanium tube corrosion. Through unremitting efforts, the maximum operating cycle of the equipment successfully reached 45 days, significantly enhancing the operational stability of the equipment and providing strong support for improving wastewater treatment efficiency and cost control. After four years of experimental exploration, refinement, and validation, a significant breakthrough has been achieved in the comprehensive treatment process for high-salinity wastewater. A low-temperature evaporation and concentration process for high-salinity wastewater, featuring a short process flow, low energy consumption, long life, low cost, controllable ions, high adaptability to the water quality of high-salinity and high-calcium wastewater from smelting, and controllable equipment investment and comprehensive costs, has been developed. This process also includes a salt separation step, laying a solid foundation for the green development of enterprises and the efficient treatment of wastewater. Currently, multiple links in the high-salinity wastewater recycling and utilization process have been successfully connected, meeting the conditions for the transformation of high-salinity wastewater treatment achievements. Next, Chifeng Yuntong will actively promote the transformation of scientific and technological achievements related to the "low-temperature evaporation and concentration of high-salinity wastewater + collaborative air omnipotent tower low-temperature evaporation crystallization and salt separation process" in accordance with the requirements of the Chifeng Municipal Ecological Environment Bureau for discharged wastewater. It will fully implement industrial projects, practice environmental protection responsibilities with concrete actions, and contribute to the continuous improvement of the regional ecological environment.

On April 27, the first phase of the CNI nickel-iron RKEF project in Indonesia, undertaken by the International Business Department of Minmetals Twenty-Three Metallurgical Construction, successfully produced nickel-iron, marking the official entry of the project into the trial production phase. Behind this significant milestone was the unwavering perseverance and dedication of the project team, who overcame the "three major challenges" of rotary kiln hoisting, electric furnace construction, and timely iron production over more than 700 days and nights, setting multiple new records for the company in the field of overseas metallurgical construction. Meticulous Successful Completion of Rotary Kiln Hoisting The rotary kiln for the first phase of the CNI nickel-iron RKEF installation project in Indonesia, with a diameter of 5.8 meters and a length of 130 meters, is the core equipment of the RKEF nickel-iron smelting process. Its installation quality directly affects the normal operation of the entire production line. The team innovatively adopted the "segmented pre-assembly + laser positioning" method, controlling the installation accuracy to the millimeter level. The project department organized multiple discussions, refinements, and revisions of the hoisting plan, developing a safe, economical, and efficient hoisting scheme. At the same time, they fully coordinated with the supervision and construction parties, carefully reviewing each construction phase. Before hoisting, comprehensive inspections were conducted on the crane, ground, slings, and equipment body, and all workers were briefed on safety techniques. The project began on-site bearing seat grinding in November 2023; in December 2023, the base and support rollers were hoisted, and the cylinder was assembled on the ground; in January 2024, the first section of the cylinder was officially hoisted, and over 1,000 mt of the kiln body was hoisted within one month, completing the aerial welding of the cylinder in just 10 days, setting a new industry record for efficient construction. Chasing the Wind and the Moon Ensuring Smooth Progress of Electric Furnace Construction The rectangular electric furnace involved in the first phase of the CNI nickel-iron RKEF installation project in Indonesia had only been constructed by China Fifteenth Metallurgical Construction domestically, and the furnace for this project was larger in scale and more complex in process. As a key piece of equipment, the construction of the electric furnace required immense effort from the project team. Due to the remote location of the project, material procurement faced numerous constraints. To address urgent material shortages, the project department implemented a multi-point layout strategy, stationing procurement personnel domestically and in Jakarta and Kendari to ensure timely material supply. During the Chinese New Year, the project team remained on duty, implementing precise strategies and completing the installation of the electric furnace and rotary kiln with high quality. Particularly in key processes such as the refractory brick laying of the electric furnace and the refractory material pouring of the rotary kiln, the work was completed 10 days ahead of schedule, with quality indicators exceeding national standards, laying a solid foundation for the successful start of production of the electric furnace and also filling the company's gap in the field of rectangular electric furnace construction. On March 7, the 72MVA rectangular electric furnace was successfully started. ENFI, the general contractor of the project, sent a letter of commendation to the project team, praising the project management team for its outstanding professional capabilities and the spirit of overcoming difficulties during the project construction. The letter stated that the team "ensured efficient contract performance through scientific management" and "strictly controlled quality throughout the entire process," and specifically mentioned that "despite the compressed project duration, the construction tasks were completed ahead of schedule, fully demonstrating your company's strength in the field of metallurgical construction." Pursuing Excellence Striving to Achieve the Tapping Target The "April 30 tapping" period target set by the owner was unanimously regarded as "nearly impossible to achieve" by the supervisor and the general contractor. The project department implemented a "two-shift" operation mode and established an "hourly" progress control system. All members worked day and night in a fierce race against time. Focusing on the goal of tapping on schedule, the project department collaborated with the general contractor, supervisor, and other relevant units to work backwards from the project deadline, subdivide the construction characteristics of each subproject, and communicate and coordinate in advance the supply of personnel, machinery, and material spare parts. From the successful power transmission to the electric furnace on April 6, to the successful slag tapping on April 18, and then to the successful production of ferronickel on April 27, the project team set a record for the company's large-scale rectangular ferronickel electric furnace, taking only 21 days from the start of power transmission to the production of ferronickel. The tapping period was achieved 3 days ahead of the original plan. Like a boat navigating the vast sea or a horse standing atop Kunlun Mountain, the International Business Department of Minmetals 23rd Construction Group Co., Ltd. will stride forward with the tide of the times, seizing the opportunity to accelerate the construction of a new highland for metallurgical construction under the "Belt and Road" Initiative. Adhering to the development philosophy of cooperation, mutual benefit, and win-win results, the department will introduce more Chinese solutions, technologies, and construction practices to the participating countries.

In the upcoming year of 2025, we anticipate that the global economy will face a series of complex and volatile challenges. With the conclusion of the US presidential election, the uncertainty surrounding global trade policies is expected to further increase, presenting new issues for international trade cooperation. In the realm of geopolitics, ongoing conflicts and tensions show no significant signs of easing, posing threats not only to global security but also significantly impacting resource allocation and industrial layout. Against this macro backdrop, industrial relocation and supply chain restructuring have become key topics that we must closely monitor. At the industrial level, the trend of protectionism in mineral resources is on the rise, directly affecting the stability of global copper concentrate TCs. With the rapid expansion of global smelting capacity, the profit margins of copper smelters are further compressed, and the challenges faced by the industry are becoming increasingly severe. In the field of secondary copper raw materials, the advancement of Environmental, Social, and Governance (ESG) standards and the "dual carbon" goals have significantly increased market attention on secondary copper. However, the "reverse invoicing" policy implemented in 2024 and the "Fair Competition Regulations" have had a profound impact on the secondary copper industry. Looking ahead to 2025, the changes in the landscape of the secondary copper industry will have a critical impact on the entire copper industry chain. Additionally, with the cancellation of tax subsidies and other incentive measures, the space for copper cathode trade is expected to further narrow. We anticipate that the procurement ratio of copper processing materials between traders and smelters will show a more pronounced differentiation. In this context, the "CCIE 2025 SMM (20th) Copper Industry Conference and Copper Industry Expo," meticulously prepared by SMM, will be grandly held in Nanchang, Jiangxi, from April 22-25, 2025. Shandong Humon Smelting Co., Ltd. will make a splendid appearance at this conference. We will keep pace with the times, aim for our goals, strive diligently, and move forward with courage and determination! Click the registration form to sign up immediately, and we look forward to meeting you at the conference. Booth number: B10. Shandong Humon Smelting Co., Ltd. was established in 1988, restructured into a joint-stock company in 1994, listed on the Shenzhen Stock Exchange in May 2008, and became a subsidiary of Jiangxi Copper Corporation in 2019. Currently, the company is a specialized enterprise in China with a relatively comprehensive integrated system for gold-copper, gold-lead, and rare and semi-metal mixed smelting and refining. Additionally, the company is extensively engaged in non-ferrous metal mining, sulfur chemical industry, high-purity metal material R&D and production, and international trade of mineral resources. The company is located in Yantai, Shandong, one of China's first 14 coastal open cities.

The company's comprehensive supporting capacity for precious metal smelting is at the leading level in China, with several technologies in the field of complex ore processing being internationally leading. Currently, the company has established multiple sets of cyanide-free environmental protection metallurgical process production systems. Through independent innovation, the company has successfully achieved a breakthrough in the rapid cooling dry arsenic collection technology in the oxygen-enriched bottom-blown smelting system and developed a refined arsenic trioxide-metallic arsenic production line, integrating arsenic treatment and industrialization, creating the Humon model for global arsenic treatment. As a result, the company has also received significant support from the National Development and Reform Commission (NDRC) for the "Solid Waste Resource Utilization" major project. The company has also successfully applied the pulverized coal bottom-blown direct reduction technology in the high-lead gold capture process system, becoming the first professional factory in the world to master this technology. On this basis, the company has further developed production technologies from metallic arsenic to high-purity arsenic to semiconductor compounds and expanded the R&D and production of high-purity selenium, high-purity tellurium, and sulfur-based glass. These high-end materials are important raw materials for fields such as aerospace. Currently, the company has achieved supply to domestic top-tier enterprises in the microelectronics semiconductor field, allowing China's high-end core equipment to use its own materials, solving the "bottleneck" problem for the country. The company regards innovation as the lifeblood of the enterprise. In recent years, the company has vigorously implemented the "three major innovations" strategy in concepts, technology, and management, driving the enterprise onto a path of sustained, rapid, and healthy development. Especially in the field of technological innovation, the company has established stable cooperative relationships with several well-known domestic universities and research institutes such as Central South University, Northeastern University, and China ENFI, and has gone abroad to carry out long-term cooperation with well-known peer enterprises in Chile and Canada, tackling key technologies and achieving multiple breakthroughs.
