热酸浸出-低污染沉矾工艺的生产实践

摘要

介绍了热酸浸出-低污染沉矾的工艺原理和该工艺在某企业的生产实践，针对原料含铁高造成沉矾工序操作不稳定，在预中和时出现黄铁矾早熟，造成除铁效率降低，渣含锌等问题进行讨论。%This paper introduces zinc hydrometallurgy process of low pollution jarosite process in hot acid Leaching and production practice in Chifeng non -ferrous of China zinc industry limited company . In this thesis , it is mainly discussed the unsteady operation of jarosite process and the Zinc Content in the Lead -Silver Slag.
