SMM March 20 News: According to an official announcement from Qingdao Manganese Series Investment Partnership (Limited Partnership), it invites qualified bidders to submit sealed bids for the selenium dioxide project for electrolytic manganese production. Component requirements: SeO₂ ≥ 98%. Total tender quantity: Approximately 169 tons. Bid deadline: 9:00 AM (Beijing Time), March 23, 2026.

SMM News, June 25 – According to an official announcement from Jinguan Copper, a subsidiary of Tongling Nonferrous Metals Group Co., Ltd., the company began publicly selling 32 metric tons of crude selenium yesterday, though the reserve price was not disclosed. The deadline for bid submissions is June 25, 2025. Market observers noted that the one-day bidding window suggests the seller has strong confidence in offloading this batch of crude selenium. Recently, many selenium producers have ramped up tenders for selling selenium products. Some manufacturers have increased shipments ahead of mid-year, putting downward pressure on selenium prices. The rise in crude selenium supply from producers has sustained market oversupply, keeping prices weak across selenium products—including selenium dioxide—with a clear downward trend. Some analysts also highlighted that the outcome of Tongling Nonferrous Metals Group’s tender will be crucial, as it may indicate the price resilience of crude selenium. SMM will continue to monitor developments.

SMM News on June 23: According to the official announcement from Jingxi Daxinan Manganese Industry Co., Ltd., the company is preparing to conduct an open inquiry-based procurement for selenium dioxide.

The deadline for quotation submission is 9:00 a.m. (Beijing time) on June 23, 2025. Suppliers must complete the quotation submission for the procurement project on the centralised procurement platform before the deadline.

On June 13, at the 2025 SMM (13th) Minor Metal Industry Conference - Rare and Scattered Metals Forum (Indium, Germanium, Gallium, Bismuth, Selenium, Tellurium), hosted by Shandong Humon Smelting Co., Ltd. and SMM Information & Technology Co., Ltd., Long Wensheng, General Manager of Changsha Aochang Nonferrous Metals Co., Ltd., elaborated on "The Current Application Status and Future Prospects of Minor Metal Selenium.

SMM May 16 News: After a period of stable consolidation in the domestic selenium product market prices, entering the first half of May, the demand from the terminal sector continued to show a weak off-season trend. Additionally, many manufacturers began to tender for crude selenium, causing the overall selenium prices to weaken slightly. However, as the current selenium prices are at a historical low over the past three years, the overall cost of selenium restricts many manufacturers from further reducing their selling prices, especially for selenium powder and selenium ingots. Nevertheless, due to the recent increase in tenders for selenium products such as crude selenium in the market, the prices of crude selenium and selenium dioxide have still weakened. According to official news from Daye Nonferrous Metals Group Holding Co., Ltd., 15 mt (metal content) of crude selenium, which was recently put up for public sale, has been successfully traded. SMM learned that the official starting price was 140,000 yuan/mt (metal content), and market rumors suggest that the difference between the starting price and the final transaction price was relatively small. According to official news from Guangxi Nanko Copper Co., Ltd., bidding sales for 4,000 kg of selenium ingots (99.99%) under its banner began today. The specifications and model are as follows: Cu: ≤0.0003; Hg: ≤0.0003; As: ≤0.0005; Sb: ≤0.0005; Te: ≤0.0010; Fe: ≤0.0010; Pb: ≤0.0005; Ni: ≤0.0005; Bi: ≤0.0005; Mg: ≤0.0008; Al: ≤0.0008; Si: ≤0.0009; B: ≤0.0005; S: ≤0.004; Sn: ≤0.0005; total impurity content: ≤0.01, packaged in wooden boxes. The official starting price was not disclosed. The deadline for this quotation is 10:50 on May 16, 2025. Currently, market participants are closely monitoring the ongoing and future tender situations. At present, the average price of SMM crude selenium is 142.5 yuan/kg, the average price of selenium dioxide is 117.5 yuan/kg, the average price of 99.9% selenium powder is 195 yuan/kg, and the average price of 99.99% selenium powder is 280 yuan/kg.

Against the backdrop of global economic recovery, the silver industry chain is ushering in new development opportunities. As one of the important precious metals, silver not only plays a role in value preservation and investment in the financial market, but is also widely used in various fields such as the electronics industry, healthcare, solar cells, and automotive manufacturing due to its excellent conductivity, thermal conductivity, and antibacterial properties. To further promote the sustainable development of the silver industry and strengthen communication and cooperation within the industry, the 2025 SMM (6th) Silver Industry Chain Innovation Conference is planned to be held in May 2025. In recent years, with the growing global demand for renewable energy and high-tech products, the industrial application demand for silver has significantly increased. At the same time, global economic uncertainties and changes in monetary policies have also prompted more investors to pay attention to silver's safe-haven attributes. As an important global commodity market, the attention to the silver industry chain in Asia, North America, and Europe has gradually increased, with local policies, technological innovations, and market demand changes bringing profound impacts on the entire industry chain. At this conference, Shandong Humon Smelting Co., Ltd. will make a grand appearance, joining peers from the upstream and downstream of the silver industry to focus on various aspects such as mining, processing, trade, investment, and application of silver, comprehensively discussing the challenges faced by the industry and future development opportunities.

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!
