Beschreibung
Zusammenfassung:	FIELD: mining industry. SUBSTANCE: method can be applied in flotation of potassium, phosphates, and other components and, more specifically, when concentrating sylvinite ores. According to invention, additional collector is provided, namely, catalytic gas oil, or 1:3 mixture of catalytic gas oil 120-350 C fraction with 350-500 C fraction, or 1:1 mixture of catalytic gas oil fraction with boiling range above 350 C and 150-300 C fraction, in amounts 50 to 100 g/t. EFFECT: increased isolation of extreme size fractions and reduced collector consumption. 2 tbl
