METHOD FOR PROCESSING THE TAILINGS OF CYANIDATION OF CRYSTALLINE FRACTION OF GOLD-CONTAINING PULP

摘要

FIELD: hydrometallurgy of noble metals in processing of tailings of cyanidation of pulp crystalline fraction. SUBSTANCE: method involves washing the tailings of cyanidation and dewatering the dump sands. A part of dump sands is additionally washed from cyaline with pure water with its consumption of 6-8 cu. m per ton up to cyanide content in solution equalling 0.03-0.05 mg/l of the amount proportional to the volume of washing water. Washing solution is supplied for washing tailings of cyanidation. EFFECT: higher efficiency.
