[0002] A flotation cell, short for flotation concentrator, refers to the mechanical equipment used to perform the flotation process. In a flotation cell, ore pulp treated with reagents is agitated and aerated, causing certain mineral particles to selectively attach to bubbles. These particles rise to the surface of the pulp and are scraped off as a froth product, while the remainder remains within the pulp, achieving the goal of separating the minerals. Bubble flotation cells are essential for gold recovery from gold-bearing ore.

Then, some mineral particles in the gold-containing slurry are selectively fixed on the bubbles, and the bubbles are floated on the top of the slurry. Finally, the blowing pump 13 is started to blow air into the inner cavity of the flotation tank 2, and the flotation foam is allowed to enter the foam outlet trough 3 by wind force, and the foam is allowed to fall from the front end of the foam outlet trough 3 into the foam receiving trough 5. In addition, the second motor 10 is used to drive the first reciprocating screw 9 to rotate, and the threaded fit between the first reciprocating screw 9 and the movable seat 11 is used to drive the movable seat 11, the blowing box 12 and the blowing hood 15 to move back and forth horizontally, ensuring that the flotation tank 2 and the foam outlet trough 3 are completely blown and the foam is completely blown out.
