Current State Of Copper Smelting Slags And Their Processing: A Review
Keywords:
slags, depletion process, sulphidation of oxidized compounds, magnetite reduction, bubbling of a bath, coalescence of small particles, poor matte, waste product
Abstract
The review article is devoted to the current state and ways of solving one of the most pressing and complex problems in copper metallurgy - the reduction of irrecoverable losses of metal with dump slags and the creation of environmental technology. 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 sulfiding of oxidized copper compounds, the reduction of magnetite in the slag to wustite, and the creation of conditions for the coalescence of fine drops of matte. Creating these conditions makes it possible to reduce the residual concentration of copper to the level applied. This can be obtained poor matte, which is processed by pouring them into a melting furnace. Depleted slag is waste products and can be implemented in the construction industry. In fact, this makes it possible to abandon the creation of slag heaps
