METHOD OF FLOTATION CONCENTRATION OF ORES Russian patent published in 2006 - IPC B03D1/02 

FIELD: mining; methods of the flotation concentration of ores.

SUBSTANCE: the invention is pertaining to the field of mining, in particular, to the method of the flotation concentration of ores and may be used to increase the effectiveness of the action of the cationic collector at processing of potassium ores or other types of minerals. The invention allows to increase floatability of the coarse fractions of sylvite, to ensure stable indexes of floatation of the potassium chloride at the seasonal fluctuations of the recirculated brine temperature from 18 up to 35°C. The method provides for the ore comminution, its desliming and the floatation of potassium chloride. Amines with the ratio of the mass shares of the amines C₁₈ and C₁₆ fractions of no less than 2.7:1 and no more than 4.0:1 accordingly are used in the capacity of the reactant-collector.

EFFECT: the invention ensures the increase of the effectiveness of the action of the cationic collector at processing of potassium ores or other types of minerals.
