en.Wedoany.com Reported - In the first half of 2026, facing the complex situation of tight supply and demand for global copper smelting raw materials and sustained pressure on processing profits, Daye Nonferrous Metals Group Holdings Co., Ltd. (hereinafter referred to as "CNMC Daye"), a subsidiary of China Nonferrous Metal Mining (Group) Co., Ltd., focused on the main line of "stabilizing operations, ensuring funds, reducing costs, and controlling risks." Its refined copper and sulfuric acid output reached 101.64% and 111.02% of the annual decomposition plan, respectively, achieving profits significantly exceeding the milestone target and successfully completing the task of "half the time, half the target" with high quality.
In the coordinated operation of the mining and smelting sectors, CNMC Daye started by optimizing mining and beneficiation processes, focusing on the efficient recovery of associated resources. It cumulatively recovered an additional 7,957 tons of standard sulfur resources (equivalent to 35% grade), effectively supplementing the supply gap of copper concentrate. Guided by the principle of "stabilizing copper, increasing acid," the smelting sector broke through process ratio limitations. The acid-to-copper ratio at the smelter was optimized from 3.76 to 4.0, while at Hongsheng Copper it increased from 3.8 to 4.23, resulting in smelting acid output exceeding the plan by 4%. The precious metals business seized price fluctuation windows, achieving gold and silver recovery rates exceeding 99%, realizing stable and high production alongside improved quality and efficiency.
In terms of technological innovation and intelligent transformation, CNMC Daye empowered the upgrading of traditional industries through intelligent and digital transformation. The construction of intelligent mines was accelerated comprehensively. Tonglüshan Mine coordinated 20 equipment upgrades, with 7 intelligent units put into operation, and achieved remote centralized control of drainage, ventilation, and hoisting systems. Tongshankou Mine's intelligent control center enabled remote operation of underground LHDs, and unmanned electric locomotives entered normal operation. Fengshan Copper Mine deployed a full-information visualization system, achieving digital control over the entire measurement and inspection process. Technological innovation yielded fruitful results. The Precious Metals Branch successfully produced high-purity selenium and high-purity tellurium. The smelter overcame technical barriers in low-temperature waste heat recovery for a million-ton sulfuric acid plant. Technological innovation is accelerating its transformation into new profit growth points.
In terms of safety and environmental protection, CNMC Daye insists on this as the prerequisite and bottom line for enterprise development. In safety work, the company's leadership team led regular supervision and inspection efforts, focusing on key areas such as open-pit slopes, tailings ponds, hazardous chemical production, and construction. Entering the flood season, the company conducted a thorough inspection of tailings ponds, open-pit slopes, and underground drainage systems, pre-stocked flood prevention materials, and formed emergency teams to ensure safe passage through the flood season. In environmental governance, the company issued the "2026 Work Task List for Promoting the Construction of a Beautiful China." Hongsheng Copper's distributed photovoltaic project entered trial operation. Ecological restoration of the Tongshankou Mine waste dump was fully completed. The smelter's sulfur dioxide emissions were reduced by approximately 56.8% year-on-year.
Through systematic planning and precise implementation, CNMC Daye delivered a high-quality "mid-term report card." In the second half of the year, all cadres and employees of the company will go all out to achieve the annual targets.
