Quality of copper concentrate impacts smelter emissions
2021-11-18 For example, in the Kamoa mine in the DRC nearly 70% of mineralogy consist of the high copper content bornite, covellite and chalcocite. The above-mentioned mineralogy results in concentrate quality at above ~60% copper content. Finally, the copper rich minerals include significantly less iron, which drives a quality challenge at the process plant.
