Biological oxidation of polymetallic ores as a potential possibility for the treatment of ore from the Coka Marin

Abstract

Coka Marin is a polymetallic deposit which in addition to desired metals contains Hq and As, so that the concentrate produced by the ore processing from this deposit cannot be processing in smelter in Bor. Plants for treatments of ore with mentioned content by using pretreatment the biological oxidation exist in world for many years. This plants are proved to be good alternative to pyro metallurgical processes of ore processing. The advantage is ecological and economical. For these reasons it would be useful to investigate the possibility of the application of this procedure on the concentrate obtained from ore Coka Marin.
