2026 marks the opening year of the “15th Five-Year Plan”. Against the backdrop of intensifying global macro volatility and the deepening advancement of high-quality development in China, the zinc industry is undergoing profound transformation: tightness at the ore end and the release of smelting capacity are creating structural tension; divergence between domestic and overseas inventory reflects the complex dynamics of supply and demand rebalancing; and technological innovation is becoming the key momentum to resolve contradictions and reshape the landscape. Key “15th Five-Year Plan” sectors such as new energy and new-type infrastructure are injecting fresh momentum into traditional zinc consumption, while green, low-carbon development and the circular economy are also accelerating the reshaping of industrial logic under the drive of technological innovation. With the joint support of upstream and downstream enterprises in the zinc industry, industry associations, and other relevant parties, SMM the 2026 SMM Zinc Industry Conference and the 8th Hot-Dip Galvanizing Industry Development and Technological Innovation Forum, and the 14th Zinc Salts, Zinc Oxide and Secondary Zinc Resources Development Forum, and the Casting Zinc Alloy Development Forum are about to be held in Qingdao, Shandong, from August 6 to 8. Under the theme “Harness Zinc Momentum · Build the Zinc Industry · Embark on a New Journey”, the conference will be driven by a dual engine of macro perspective and fundamentals analysis, closely aligned with the main line of high-quality development under the “15th Five-Year Plan”. It will focus on four key dimensions—macro policy, the supply-demand pattern, global trade, and technological innovation—leveraging technological breakthroughs to drive cost reduction and efficiency improvement, and using collaborative innovation to address market fluctuations, jointly charting a new blueprint for high-quality and sustainable development of the zinc industry.‌ Jiangsu Myande Energy-Saving Evaporation Equipment Co., Ltd. will make a distinguished appearance at this grand event, joining industry peers to discuss industry development trends and work together to propel the zinc industry to new heights.

System Solution for Resource Utilization of High-Salinity Wastewater in the Metallurgical Industry From “High-Salinity Burden” to “Resource Gains”—Empowering Green and Intelligent Manufacturing in Zinc Smelting I. Wastewater Treatment Challenges in the Secondary Zinc Industry A large volume of high-salinity wastewater is generated during zinc recovery from zinc-containing scrap, requiring compliant environmental protection treatment with stringent standards. This results in both high investment in environmental protection equipment and high subsequent operating costs, compressing enterprise profit margins. Moreover, secondary waste is generated after environmental protection disposal, adding disposal costs and making it difficult for enterprises to continue bearing the burden. II. Root Causes of Wastewater Treatment In the zinc recovery process for zinc-containing scrap, low-grade zinc oxide must be rinsed to remove chlorides and other impurities in the raw material to avoid affecting the purity of zinc products. In addition to sodium chloride and potassium chloride, the rinsing wastewater also contains sulphate radicals, fluoride, COD, and many other components. Its composition is complex and fluctuates significantly, making wastewater treatment highly challenging. III. Three Core Processes, One-Stop Breakthrough 1. Deep pre-treatment—precisely removes fluorides, heavy metals, and organic matter, ensuring long-term stable operation of the system 2. Evaporation Concentration + Fractional Crystallization—Recovering High-Purity Potassium Chloride and Sodium Chloride, Achieving Salt Resource Recovery 3. Evaporative Condensate Reuse in Production Processes—Self-Circulation of Process Water, Achieving True "Zero Discharge" 4. Dual Benefits Empowering Enterprises Turning high-salinity wastewater into a valuable resource, while achieving environmentally compliant disposal, recovering salt resources, with revenue covering operating costs, shortening the payback period, and enhancing overall economic benefits.

“Tin” Guiding the Future: Industrial Transformation and Value Reshaping in a New Cycle Conference Background Currently, the global tin industry stands at a historic turning point. The logic of traditional cycles has been completely shattered, and its strategic value is fully emerging. The tin market in 2026 presents an unprecedentedly complex pattern and profound transformation: 1. In-depth reconstruction of the supply-demand pattern, with its strategic attributes elevated to an unprecedented level. The global static reserve-to-production ratio of tin is only 14 years, and its scarcity is increasingly pronounced. The supply side faces “triple pressure”: repeated setbacks in Myanmar’s production resumptions, continuously tightening policies in Indonesia, and high geopolitical risks in the DRC. Resource constraints have already become the new normal. Meanwhile, a fundamental shift is taking place in the demand structure. Tin has become a strategic resource bridging traditional manufacturing and the digital future. 2. A historic breakthrough in the price system, reshaping the industrial ecosystem. In early 2026, SHFE tin prices breached 470,000 yuan/mt, setting a new record high. This price breakthrough not only reflects the supply-demand imbalance but also marks a revaluation of the tin industry. Traditional trade models, risk management systems, and supply chain collaboration methods all urgently require innovative breakthroughs. 3. Technology-driven innovation and the green transition are fostering a new symbiotic ecosystem. Digital and intelligent technologies are deeply empowering the tin industry chain. The global green transition requires the tin industry to upgrade toward low-carbon and circular economy models, making recycled tin recovery and green smelting processes essential paths. All links in the industry chain must move from competition to collaboration, building an open, resilient, and innovative symbiotic system. Against this backdrop, the August 19-21, 2026 in Changsha, Hunan held 2026 SMM (16th) Tin Industry Chain Conference will bring together global industry elites for discussion. Yunnan Tin Co., Ltd. will attend this grand event, discuss industry development trends with peers, and jointly propel the tin industry to new heights.
