Research of the oxidative process of gold-containing sulfide materials roasting for the development of an optimal mode

Now, in world practice, sulphide refractory gold-containing materials are subjected to oxidative roasting mainly with low productivity and subsequent cyanidation provides a high degree of metal recovery. Of particular importance is oxidative calcination to increase the extraction of valuable components (Au, Ag, Mo, W, Cu, Zn) from metal-containing intermediate products. Today, new technologies and technological schemes are being developed around the world in the field of processing gold-bearing ores to increase the degree of extraction and reduce processing costs in order to reduce the cost of the product, and special attention is paid to reducing the content of a valuable component in the tailings of processes, as well as special attention paid to reduce the content of a valuable component in the tailings of production processes. In this aspect, the development of new technologies and the improvement of existing technologies to increase the extraction of valuable components are urgent tasks of the science and practice of the mining and metallurgical industry. The aim of the research was to develop an effective technology for processing sulfide materials in suspension in a kiln to intensify the process and increase the yield of valuable components.
