Abstract
This paper describes the composition of technogenic waste after flotation of copper production slags and the sequence of experiments on extraction of valuable components from them. Initially artificial mineral contained in technogenic waste fayalite was subjected to thermal decomposition in the presence of air, and then from the resulting slag copper was selectively leached in acidic medium. In the process of leaching copper passed into solution, as a result of hydrolysis iron remained in the cake. The solution was filtered and copper was precipitated with sodium sulfide. At the end of the processes, the copper sulfide precipitate was filtered and dried. The conversion rate of copper from the anthropogenic waste to the sulfide precipitate was 88.7 percent.
