METHOD OF CONCENTRATING SULFIDE SIDERITE-CONTAINING ORES Russian patent published in 1998 - IPC

Abstract RU 2123885 C1

FIELD: ore concentration in nonferrous metallurgy. SUBSTANCE: preliminary treatment of sulfide siderite-containing ores is conducted in pulp by electric explosion with specific energy of 50-150 kJ/cu.dm. Then pulp is subjected to magnetic separation and flotation. EFFECT: improved quality of concentrate of nonferrous metals and increased quantity in complex utilization of mineral raw materials. 1 tbl
