摘　　要：介绍了河南金利金铅集团有限公司新建铅基多金属固废协同强化冶炼产业化示范及锌资源综合利用项目,特别是侧-顶吹熔炼技术处理铅基固废等物料的生产实践。总结了生产情况,阐述了主要生产工艺,列举了主要的生产数据和技术经济指标。国内锌冶炼多以湿法冶炼为主,在其生产过程中会产出含铅的锌渣。以前由于技术落后,该渣多以堆存为主,近些年由于环保问题亟需对该固废进行处理,由此出现各种小型化处理该固废渣的方法。但因该固废渣有价金属较少,处理成本较高,单独处理不经济。本文侧-顶吹熔炼技术的应用,解决了以往锌湿法冶炼产出的含铅锌渣长期堆存造成环境污染和小型化处理且成本普遍较高、不经济的问题。实践证明,侧-顶吹熔炼技术在处理含铅基固废、锌冶炼渣等物料方面是可行的,优势明显,实现了固废资源化综合利用,并且该技术工艺先进、成本较低,可实现规模化、大型化生产。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 wil 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.
