FIELD: mining.
SUBSTANCE: method of flotation of fluorite ores comprises crushing ore, stabilization of the energy state of the flotation disperse system on Eh, flotation using the reagent-collector as N-acyl-sarcosine, and the reagent-depressant as liquid glass. Modification of liquid glass is carried out by adding into its composition of zinc sulphate in a ratio of zinc sulphate:liquid glass equal to (0.05÷0.53):1, and the weight ratio of the depressant to the collector is equal to 1.25÷2.5.
EFFECT: improvement of quality of fluorite concentrates, improvement of selection of fluorite and carbonate rock-forming complexes under conditions of low temperatures.
