METHOD FOR FLOATATION DRESSING OF POTASSIUM ORES

摘要

FIELD: mining. ^ SUBSTANCE: method comprises the ore reduction, sylvite floatation and dehydration of the dressing end product. The preliminary feeding processing of the sylvite primary and cleaner floatation is performed with use of the organic depressant with the following slime floatation extraction from the industrial products of the cleaner sylvite floatation. ^ EFFECT: characteristics of floatation potassium ore dressing are improved and extraction of potassium chloride to the end product is increased. ^ 3 dwg, 1 tbl, 2 ex
