ABSTRACT:
The invention relates to a method for smelting sulfidic copper concentrates, in which method copper sulfide bearing material is smelted in a smelting furnace (1) for creating blister copper and slag. According to the method, at least part (3) of the feed of the smelting furnace (1) is copper sulfide bearing (3) material obtained by means of sulfide bearing material (2) that is fed into the hydrometallurgic further processing (12,19) of slag (11) created in the smelting process.
