Description

The copper industry at different operational stages produces large volume of wastes. During matte smelting stage slag becomes one of the waste materials that occupies significant territories causing environmental issues. The matte smelting slag contains Si, Fe, Cu, Zn and S. The technological scheme for recycling of copper smelting slags with subsequent obtaining valuable products was provided in present work. The scheme includes solid-state reduction of Fe with further smelting operation for separation of the produced cast iron from slag. During solid-state reduction Zn vapor was trapped. After smelting operation cast iron contained about 1 mass % Cu and 1 mass % S; it was used for production of cast iron grinding media with improved mechanical properties enabling their application for milling of ore minerals. The silicate slag freed from Fe was used for obtaining proppants. The following products are suggested for a Mini Mill plant: cast iron grinding media for crushing of ore minerals and proppants for oil industry.
