摘要
锌浸出渣是具有资源禀赋和环境危害双重属性的湿法炼锌副产物,其处理对于资源回收和环境保护具有重要意义.在国内已成功应用多种锌浸渣处理技术如热酸浸出、回转窑挥发、烟化炉烟化、顶吹熔炼、侧吹熔炼和二氧化硫还原浸出等,但距离固体废物减量化、资源化、无害化的要求还有一定差距.本文从固体废物减量化、资源化、无害化的角度分析了我国锌冶炼浸出过程产出渣的特点,并对现有的锌浸渣工业处理技术特点及应用现状进行了分析与比较,总结了锌浸渣处理的难点,最后提出建议和展望.
Abstract
Zinc leaching residue from zinc hydrometallargy is a kind of solid waste with both resource endowment and environmental hazard.Treating zinc leaching residue is of great significance for resource recovery and environmental protection.Various zinc leaching residue treatment technologies have been successfully applied in China,such as hot acid leaching,rotary kiln volatilization,fuming furnace fuming,top blowing smelting,side blowing smelting,and sulfur dioxide reduction leaching.However,there is still a certain gap in meeting the requirements of solid waste reduction,resource utilization,and harmless treatment.In this paper,characteristics of residue generated in the zinc leaching process and present industrial treatment of zinc leaching residue were discussed from the perspective of solid waste reduction,resource utilization and harmlessness.The difficulties of treatment for zinc leaching residue were discussed.Finally,suggestions and prospects were put forward.
