METHOD OF PRODUCING METAL-CONTAINING VALUABLE SUBSTANCES FROM METAL-CONTAINING VALUABLE SUBSTANCES OF SUSPENSION MASS FLOW Russian patent published in 2016 - IPC B03D1/24 

FIELD: metallurgy.

SUBSTANCE: invention relates to a method of production metal-containing valuable substances from a suspension containing valuable metal substances. Method of producing metal-containing valuable substances from a suspension containing valuable metal substances, wherein the initial suspension is pressurised in at least one pumping device, then fed along at least one supply pipeline via at least one nozzle device into at least one flotation chamber. In the flotation chamber the metal containing valuable substances are separated. After passing through the pumping unit and before entering the nozzle device, gas is supplied into the suspension with valuable metal-containing substances so that the pressurised suspension is filled with the gas. Method is implemented using a device comprising at least one pumping unit for supply of initial suspension with metal containing valuable substances through the supply pipelines and nozzle device into at least one flotation chamber. Between the pumping and the nozzle devices there is located at least one device for injection of gas into the suspension.

EFFECT: technical result is increased efficiency of floatation.
