ARTICLE ANNOTATION

quote
The article discusses the problems of reducing copper losses with waste slag. A comprehensive solution to the problem with the use of physicochemical methods of influence on the melt is proposed. It is shown that the success of the depletion process depends on the sulfidation of oxidized copper compounds, the reduction of magnetite in the slag to wustite, and the creation of conditions for the coalescence of small drops of matte. The creation of these conditions makes it possible to reduce the residual concentration of copper to the applied level. In this case, poor matte can be obtained, which is processed by pouring them into melting furnaces. Depleted slag is a waste product and can be implemented in the construction industry. In fact, this makes it possible to abandon the creation of slag dumps
