FLOTATION PROCESS FOR SULFIDE ORES AND CONCENTRATES CONTAINING FADED ORES, CHALCOPYRITE, AND PYRITE

摘要

FIELD: mineral dressing. SUBSTANCE: process may by used for separating pyrite-containing, copper sulfide, copper-zinc, and copper-molybdenum concentrates. Process includes conditioning of slurry in alkali medium with collector and flotation. According to invention, conditioning is performed at pH 9.5-10.0 and collector employs ethyldithiocarbamates with general formula R-NH-CS-S-CH₂CH₂CN where R is cycloalkyl, alkyl or aryl. EFFECT: enhanced efficiency of process. 3 tbl
