INSTALLATION FOR EXTRACTION OF MINERALS CONTAINING HEAVY METALS Russian patent published in 1999 - IPC

FIELD: extraction of minerals containing heavy metals. SUBSTANCE: installation metals such as thorium and uranium has a jigging chamber with a diaphragm, movable sieve, vibrating drive, upper and lower accumulators of jigged fractions. The movable sieve is furnished with a frame connected to the telescopic rod of the vibrating drive, and by means of rigid intermediate couplings and an axle it is engageable with the diagram; the L-shaped end of the diaphragm is engageable with the guide stop of the upper accumulator of jigged fractions. The movable sieve and the lower accumulator of jigged fractions are made with accumulators for fractions with a higher density, furnished with covers- accumulators for fractions with a lower density and inclined towards jigging, and inclined towards unloading. EFFECT: enhanced efficiency of concentration of minerals within a narrow band of density. 2 dwg
