FIELD: metallurgy.
SUBSTANCE: method includes concentrate leaching by spillage solutions of sulfureous sodium in solution of caustic soda with receiving solutions of sodium tri-sulphantimonite and mercury- sodium sulfide complex and insoluble residue and direction of received solution to electrolysis. Additionally electrolysis is implemented with extraction of stibium and mercury in the form of cathodic mercury-antimonial metal, 70% of electrolyte after electrolyze electrolysis is returned to leaching of concentrate. From cathodic mercury-antimonial metal by distillation by means of heat treatment it is removed mercury with receiving of mercury of grade P-1. Distillation residual is directed to reverberatory process and refinement for receiving of stibium Cy0, Cy00.
EFFECT: increasing of mercury and stibium extraction into self-contained marketable product.
