NOUFERROUS METALLURGICAL EQUIPMENT

This paper introduces the newly-built project of Henan Jinli Gold-Lead Co., Ltd.: demonstration of lead-based metal solid waste collaborative strengthening smelting industrialization and comprehensive utilization of zinc resources, especially the production practice of side-top blowing smelting technology to treat lead-based solid waste and other materials. This paper summarizes the production situation, expounds the main production technology, and lists the main production data and technical and economic indicators. Domestic zinc smelting is mainly based on wet smelting, and lead-containing zinc slag will be produced in its production process. In the past, due to backward technology, the slag was mainly stored in storage. In recent years, due to environmental problems, the solid waste must be treated. Therefore, various methods of miniaturization treatment of the solid waste residue have emerged. Because there are few valuable metals in the solid waste residue and the treatment cost is high, it is not economical to treat it alone. However, the application of side-top blowing smelting technology has solved the problems of environmental pollution caused by long-term storage of lead-containing zinc slag produced by zinc hydrometallurgy in the past, or high cost and uneconomical feature caused by miniaturization. Practice has proved that the side-top blowing smelting technology is feasible and has obvious advantages in treating lead-based solid waste, zinc smelting slag and other materials, and realizes the comprehensive utilization of solid waste resources. Moreover, the technology has advanced technology and low cost. Through production practice, it is proved that the technology can realize large-scale production.
