Abstract
The article discusses the issues of processing slag of copper production using devices that model ideal mixing. It has been shown that the use of this type of apparatus increases the efficiency of physical and chemical processes and significantly reduces the copper content in dump slags. It has been found that the process of reduction of ferric iron oxide by the clinker in the initial period takes place in the kinetic mode. After reducing the concentration of magnetite (3-5%) in the slag, the process of reducing it passes into the diffusion region, that is, restoring the excess content of ferric iron in iron silicate melts takes a short period of time during which the process can be carried out, without significantly delaying the operation time of the main industrial equipment. The optimal slag magnetite reducing agent is determined to be zinc production waste
