Abstract

The invention relates to a flotation apparatus improving the recovery of concentrate remaining with tailing. The apparatus according to the invention comprises a cell (1) for treating the ore to be beneficiated and the materials added thereto, i.e. the head material, a feed pipe (2) leading to the cell for feeding head material into the cell (1), a froth chute (3) disposed in the top portion of the cell (1) for collecting concentrate rising up in the cell, and a discharge duct (4) disposed in the lower portion of the cell for conveying the tailing out from the cell, as well as a regulating device (5) disposed in the bottom of the cell, wherethrough compressed air and water in a finely divided mixture are supplied to the cell.
