SLURRY CONCENTRATION PROCESS Russian patent published in 2001 - IPC

FIELD: mineral dressing. SUBSTANCE: invention relates to concentration of fine-dispersed, polymetallic, copper, molybdenum, and other types of ores. Initial pulp made up of water, slurries, and weighting material is treated with solution of neutral salt with concentration 0.4-0.5 g-equ/l, fed into interior of apparatus performing rotationally-reversible vibrations around inclined axis, and separated products are discharged. Regulation of structure of liquid phase of pulp by introducing neutral salts in the latter enables most full separation of slurries from coarse fraction owing to reduced viscosity of liquid part of pulp and wetted surface of particles. EFFECT: increased degree of recovery of costly components into concentrate. 5 tbl
