ABSTRACT:
A heavy metal separator for removing heavy metal particles and flakes from ore. It has a feed hopper which feeds a slurry of ore over an inclined screen in a separation chamber. The smaller particles pass through the screen into a second section of the separation chamber. The larger particles wave downwardly off the lower end of the screen into a first section of the separation chamber. A stream of water is directed by baffles upward through the second section counter current to the flow of materials. The water washes the less dense waste material out of the second section into the first section. The fine heavy metal particles and flakes, being more dense, settle downwardly to a collection point at the bottom of the second section. The larger concentrates and fine waste material move downwardly through the first section to an outlet, where they pass into a second separation chamber. An upwardly moving stream of water in the second separation chamber washes all waste material out of the separator while allowing the more dense coarse heavy metal particles and flakes to move downwardly through the water into a collection point at the bottom of the second separation chamber.
