Abstract
The research on the dispersal of slag from the slurry process was carried out in a laboratory resistance furnace. Before declaring, the slag contained 13.62% copper. In the processes of reduction of slag samples with calcium carbide in the form of carbide with activating additives Na2CO3 and CaF2, the content of copper in the slag was reduced to a level of 0.28–0.63% Cu. The polymetallic melt formed after the decoupling of the slag contained 78.55–84.9% Cu, 10.8–16.48% Pb, and 0.08–0.39% Fe.
