ABSTRACT:
A novel apparatus for use in frothless flotation. The apparatus includes a cover which is sealingly engaged to the top of the flotation column and a wash-water tank in communication with the upper part of the flotation column wherein the level in the wash-water tank is maintained at or above the level of the cover thereby preventing the formation of a froth layer in the column. The apparatus is adapted to recycle the pulp and the tails. Gas is introduced to the feed and/or recycled tails in motionless mixers. Bubble-pulp separators are provided which recirculate pulp to enhance the quality of the yield.
