METHOD OF PROCESSING SULFIDE GOLD-CONTAINING ORE Russian patent published in 2003 - IPC

Abstract RU 2198948 C2

FIELD: mineral concentration, particularly, technology of concentration of gold-containing ores; applicable in development of resource and energy saving technologies of gold recovery from sulfide ores. SUBSTANCE: method includes grinding, classification and multistage separation into gold-containing product and tailings. Multistage separation is effected by electrostatic separation. Gold-containing product is subjected after electrostatic separation to additional concentration by its further grinding, classification and subsequent separation of grainy fraction. EFFECT: reduced expenditures for recovery of gold from sulfide ores. 1 dwg, 3 tbl
