| 摘要 |
The invention consists of forming an aqueous slurry (21) of water and particles of ore carrying both metals and/or minerals which are directed at relatively high speed to hit the top of the far edges of tiny cubic cells (25) in a series of overlapping (26) trays sloped at the appropriate angle. This causes the slurry to become entrapped, swirling down towards the bottom of the cell (25) and continue back up the opposite side and then back out into the main slurry flow. The centrifugal force generated by this turbulent eddy (22) can be in the hundreds of G's. Should the metals and minerals in the slurry be electrically charged opposite to the cell (25) and cell bottom, th high G-force generated by the centrifugal force of the mini swirl causes the two oppositely charged substances to come into close contact, thereby creating a substantial electrical attraction. When in close contact, the electrical force can be thousands of G's. When charged minerals, which have metals adhering electrostatically to them, come into contact with oppositely charged material, electrons are exchanged and the metals detach and remain in the cell (25) while the less dense minerals are carried out of the cell (25) by the slurry. |
