More Information
Summary:A method for refining sulfidic copper concentrate includes feeding sulfidic copper concentrate and oxygen-bearing reaction gas and slag forming material into a reaction shaft of a suspension smelting furnace, collecting slag and blister copper in a settler of the suspension smelting furnace to form a blister layer containing blister copper and a slag layer, and discharging slag and blister copper separately from the settler of the suspension smelting furnace, so that slag is fed into an electric furnace. The method further includes feeding a part of the sulfidic copper concentrate into the electric furnace.
