METHOD FOR FLOTATION ENRICHMENT OF POTASSIUM ORES

FIELD: mining industry. SUBSTANCE: process includes grinding and desludging ore, sorting flotation feed to fineness 0.1-0.3 mm, reagent treatment and separate flotation of potassium chloride from coarse and fine (-0.3+0 mm) ore fractions. The latter flotation is carried out with amine supplemented b...

Zusammenfassung:	FIELD: mining industry. SUBSTANCE: process includes grinding and desludging ore, sorting flotation feed to fineness 0.1-0.3 mm, reagent treatment and separate flotation of potassium chloride from coarse and fine (-0.3+0 mm) ore fractions. The latter flotation is carried out with amine supplemented by polyacrylamide at ratio (0.05-0.3):1 or mixture of amine with paraffin, aromatic, naphtene hydrocarbons, or their mixture at ratio 1: 90.05-3.0), respectively, or mixture of amine with aromatic hydrocarbons and polyacrylamide. EFFECT: enhanced efficiency of flotation from fine fractions. 2 cl, 4 tbl
