METHOD OF FLOATATION CONCENTRATION OF POTASSIUM ORES

摘要

FIELD: processing minerals; processing potassium ores by floatation. ^ SUBSTANCE: proposed method includes grinding of ore, treatment of ore by flocculant and collecting reagent, floatation of slime and potassium chloride. Used as collecting reagent for floatation of slime is polyoxyrthylene glycol esters of monoalkyl phenols which have 8-12 atoms of carbon in alkyl group and number of oxyethyl groups in radical is equal to 20-30. ^ EFFECT: enhanced efficiency of desliming of ore. ^ 2 tbl, 3 ex
