刚果(金)某含碳铜钴矿选矿工艺技术研究OACHSSCD
Study on Mineral Processing Technology of a Carbon-Bearing Copper-Cobalt Ore in Congo(Kinshasa)
刚果(金)某铜钴矿的铜品位为 1.44%,钴品位为 0.27%,矿石中铜、钴均主要以硫化矿物形式存在,但由于矿石含有部分微细粒碳质物及易泥化脉石,浮选泡沫状态及技术指标较差.在优化浮选药剂制度的基础上,采用中矿集中处理工艺,闭路试验获得铜品位为 14.51%、钴品位为 2.39%、铜回收率为 92.30%、钴回收率为 80.64%的铜钴总精矿,满足冶炼要求.该工艺实现了铜、钴资源的较好回收,可为同类型资源的开发利用提供借鉴.
The copper and cobalt grades of a copper-cobalt ore in Congo(Kinshasa)are 1.44%and 0.27%respectively,the copper and cobalt in the ore mainly exist in the form of sulphide minerals,however,the flotation foam state and technical indicators are poor due to the fact that the ore contains some fine carbonaceous materials and easily-slimed gangue.On the basis of optimizing the flotation reagent system,the centralized treatment process of middlings is adopted,and the closed circuit test obtains the total copper and cobalt concentrates with copper grade of 14.51%,cobalt grade of 2.39%,copper recovery rate of 92.30%and cobalt recovery rate of 80.64%,meeting the smelting requirements.This process has achieved a relatively good recovery of copper and cobalt resources,and can provide reference for the development and utilization of the same type of resources.
