METHOD OF GRAVITY CONCENTRATION OF ORES AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2003 - IPC

FIELD: concentration of minerals; extraction of diamonds, noble metals and other minerals from raw material. SUBSTANCE: method includes introduction of pulp into separation zone, translational motion in separation zone under action of vibrations directed at angle of 10-30 deg. from horizontal plane in parallel with chute in way of motion and in counter flow and separation of extracted products. Device proposed for realization of this method includes sledge, platform at adjustable angle of inclination from horizontal plane at 10 to 30 deg. , vibration drive mounted on platform, frame mounted on hinged supports in parallel with platform, chute with sills widening towards unloading end; said chute is mounted on frame. Proposed method increases degree of concentration and improves quality of concentrate ensuring mobility of plant. EFFECT: enhanced efficiency. 4 cl, 6 dwg
