METHOD FOR PREPARATION OF ARGILLACEOUS ORES AND SLIMES FOR LEACHING Russian patent published in 1995 - IPC

Abstract RU 2036300 C1

FIELD: mineral mining and processing. SUBSTANCE: method for preparation of argillaceous ores and slimes for leaching includes mixing of fine-grain fractions with binder, hardening of obtained mixture, its positioning in zone of geotechnological object. Novelty consists in adding to ore mixture before hardening of compounds whose solubility exceeds that of leached mass by 5-10000 times. After that mixture is placed to working zone to hold it 1-30 days up to hardening. Then, rock mass is crushed and treated with solvent. EFFECT: higher efficiency. 3 cl
