Abstract—The processes of processing copper sulfide concentrate by roasting it with caustic soda without air access with the extraction of the main components (copper, iron, sulfur) were studied. After leaching and filtration of the sinter, sulfur is released into the filtrate in the form of Na2S. At the same time, the release of sulfur dioxide gases into the atmosphere is completely eliminated.
