This article showed the developed technology for processing waste from the
converter stage in the production of copper. Laboratory and industrial tests were carried out
on reducing converter slag magnetite using clinker. The other processing technology was
carried out by the enrichment method using magnetic separation and gravitational
enrichment. As a result, it was possible to obtain enrichment products that could be sent to
flotation. The shown studies make it possible to obtain additional raw materials such as sulfide
concentrates and other sources of precious metals used to convert copper matte.
