Abstract

Developed and tested in the pilot mode technology for processing sulfide gold-bearing concentrates containing carbonates, preg-robbing carbonaceous matter, arsenic, antimony and sulfur and lead concentrates containing zinc and silver. This technology includes pressure oxidation of this concentrates for extraction of sulfur, arsenic and zinc to the solution and reduction smelting of the POX cakes for obtaining refined lead and precious metals alloy. The developed technology promotes to recover 97 % precious metals and 95 % zinc and lead in commercial products and eliminates of POX cakes cyanidation
