APPARATUS FOR FINE GOLD TRAPPING Russian patent published in 1997 - IPC

FIELD: natural minerals dressing, apparatus is used for fine gold trapping in particular. SUBSTANCE: apparatus has body made in the form of drum and is mounted with capability to turn for definite angle. Body has flanges and outer partitions forming row of tanks, in which magnetically active material is placed, that creates off-beat shell of dispersed particles. The shell is kept by magnetic field created by chain of magnetic members inside body, that are turning independently of the latter. Magnetic members are located in limits of 180 - 270 deg angle. In the case, flanges, body and outer partitions are made of magnetically neutral material. As a version, apparatus is mounted at the end of washing device. During pulp motion large and light particles are passing over the shell and heavy particles of gold are penetrating inside it. EFFECT: increased productivity. 2 dwg
