Study on Mineral Processing Technology of a Carbon-Bearing Copper-Cobalt Ore in Congo(Kinshasa)
摘要
Abstract
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.关键词
