The review, based on the publications by both Russian and international researchers, presents an analysis of the problems of existing technologies for smelting copper concentrates. Three main problems requiring solutions were identified and considered: increasing the efficiency of smelting copper sulfide-containing ores by reducing the copper content in slags obtained during the conversion process; increasing efficiency, including by obtaining an additional economic effect from waste disposal; reducing the harmful impact on the environment. It was stablished that trends towards the development of new efficient, environmentally friendly and cost-effective technologies are characteristic not only of the selected research object, but also of a number of other non-ferrous metals, such as lead and zinc.
