METHOD OF FLOTATION OF SULPHIDE ORES OF NON-FERROUS METALS Russian patent published in 2010 - IPC B03D1/00 B03D1/02 

FIELD: metallurgy.

SUBSTANCE: method includes grinding, conditioning, collective copper-lead flotation in alkalescent medium with known reagents. In coolective copper-lead flotation in the capacity of collector it is used collector with technical name "Beraflot", corresponding to composition of dithiophosphates, thyon urethanes, aliphatic alcohols C₁-C₄, mixture of terpene alcohols and hydrocarbons, mixture of butyl ethers of propylene glycol, stillage bottoms from manufacturing of butyl alcohols, 2-ethylhexanol, 2-ethylhexanol axid, ethylene-propylene and ethylbenzene, with following activation of sphalerite in high-alkali medium and flotation of zinc by collector "Beraflot" from tails of collective flotation and receiving of final tailings by chamber product.

EFFECT: development of method.
