湿法炼锌浸出渣中锌的高温还原回收方法进展

Research Progress on High Temperature Reduction Recovery Method of Zinc from Leaching Residue Produced by Zinc Hydrometallurgy

湿法炼锌过程中产出大量的含锌较高的浸出渣,由渣中提取锌既是实现金属资源高效利用的要求,也是环境保护的需要。高温碳热还原法是提取渣中锌的常用方法,文章对高温碳热还原法回收浸出渣中锌进行了总结分析,为锌浸出渣中锌的资源化利用提供借鉴。

The zinc hydrometallurgy process produces a large amount of leaching slag with high zinc content.Extracting zinc from the slag is not only a requirement for efficient utilization of metal resources,but also a requirement for environmental protection.High-temperature carbothermic reduction is a common method for extracting zinc from slag.This paper summarizes and analyzes the recovery of zinc from leaching slag by high-temperature carbothermic reduction,and provides a reference for the resource utilization of zinc in zinc leaching residue.
