Abstract
The problem of dump copper slag processing is one of the actual problems, which solution can be an additional source color and ferrous metals as well as will allow improving the environmental condition in the regions of acting enterprises. The present work studies the chemistry of copper and lead solid-phase reduction reactions from synthesized compounds – ferrites, sulfides, copper and lead ortho-arsenates – with the use of calcium carbide. The properties of materials have been investigated by chemical, X-ray-phase, and physical-chemical methods. The thermodynamic analysis of some chemical reactions has been carried out.
