METHOD OF CAKING FLUOROSPAR Russian patent published in 1994 - IPC

Abstract RU 2011689 C1

FIELD: preparing ores and concentrates for melting. SUBSTANCE: during caking concentrate is mixed with complex binder. Said binder contains oil wastes and liquid glass at ratio 0.5: 1, expense being 20 mass % of concentrate. Calcination is carried out at 300-350 C. EFFECT: decreases calcination temperature, decreases energy expense, increases strength of fluorospar briquettes. 1 tbl
