METHOD FOR BENEFICATION OF MINERALS Russian patent published in 1995 - IPC

FIELD: benefication of minerals. SUBSTANCE: method includes quasi-making heavy of magnetic liquid, located in a chamber between poles of the electric magnet, creating irregular magnetic field. Effective density is diminished in the direction of gravitation as quasi-making heavy is built. Material is fed at the level of liquid layer effective density of which corresponds to the density of initial material separation. Once separation has been made, unloading of products of benefication is carried out. EFFECT: highly effective separation. 5 dwg
