Abstract:There is a special copper concentrate which contenting up to 64% copper and only 2.2% iron. The analysis of its composition and phase indicates that its main mineral is chalcocite. For this special copper concentrate with high copper and low iron, several feasible smelting schemes are proposed, including the flash furnace direct-to-blister copper smelting and side-blow smelting + top-blow converting, hydrometallurgy and roasting + leaching + electrowinning. And by comparing and evaluating of pyrometallurgy with hydrometallurgy from the aspects of external construction conditions, technology and economy, suggestions are given for the process selection.
