摘　　要：某有色冶炼企业5000 t/a电积铜生产线由于原料不足,目前处于闲置状态,为了充分利用厂房和设备,拟以含镍钴矿渣为原料,生产精制硫酸镍、硫酸钴产品。本项目以附加值较高的三元材料前驱体原料电池级硫酸镍、硫酸钴为产品,不但可获得较为丰厚的利润,而且可抢占国家产业政策鼓励的新能源材料市场,在回收镍、钴的同时还可以较低成本回收铜、锌等金属,而且实现固体废物综合利用,减少固体废物产生,产生一定环境效益。The 5000 t/a electrowinning copper production line of a non-ferrous smelting enterprise is in idle state because of insuffi‐cient raw materials.This project takes battery grade nickel sulfate and cobalt sulfate as the raw materials of ternary material precur‐sors with higher added value,which not only can obtain more abundant profits,but also can capture the market of new energy materi‐als encouraged by the national industrial policy,at the same time,nickel and cobalt can be recovered at lower cost,and the compre‐hensive utilization of solid waste can be realized.

关 键 词：镍钴矿渣 硫酸镍 硫酸钴 综合利用 环境效益
