Abstract

The article presents the results of research of chemical, material, mineralogical and rational analyses of persistent gold-bearing ore of The aristantau Deposit. The re- sults of experiments indicated the content of sulfide sulfur, organic carbon, arsenic and antimony. As a result, the technological scheme included operations for oxidative firing of the flotation concentrate. Various forms of fine-grained gold were found in pyrite, arsenopyrite, and sphalerite.
