METHOD OF EXTRACTING AND CONCENTRATING MATTERS FROM THE SOLUTIONS Russian patent published in 1994 - IPC

FIELD: hydrometallurgy. SUBSTANCE: particles with radiuses of 1.0-1.6·10^-7 cm are used as float agent for extracting matters in ion, colloid and molecular forms from water phase and gas solutions. Particles may be changed, the speed of introduction of the particles is changed by electromagnetic field. These particles may be protons and hydroxyls formed during process of unipolar processing of water or bubbles of gas being charged electrolytically. Particles may be fixed to the carrier in form of solid, liquid or gaseous surface. Gaseous inclusions or gaseous rod may be used as a carrier. When gaseous rod is used ionogenic surface-active matter with opposite charge relatively extracted component is introduced into the solution. Gas may move in one direction or in opposite direction to the movement of the flow. The method provides 100 % extraction of lanthanum, lithium, silver, gold, copper, nickel and beryllium. EFFECT: improved efficiency of the method. 13 cl
