FIELD: mining.
SUBSTANCE: invention can be used in mining industry during the mineral components extraction from the ores to improve efficiency of the processes of foam floatation separation. The method provides for addition to the initial suspension of the effective quantity of organophosphorous compound selected from the group containing polyaminepolyethermethylenephosphonate - PAPEMP, in form of acid pr salt; trialkanolamintry (ether of orthophosphoric acid), in form of acid or salt. Then the selective floatation of the product in form of particles is performed by means of the suspension barbotage till formation of the concentrate and liquid solution.
EFFECT: method ensures increased degree of extraction of the target product in form of particles out of fine ground sulphide mineral ore, and reduces the energy consumption and increases efficiency of other stages of treatment and cleaning, thus promoting the environment protection.
