The single cell flotation machine can be interconnected to a number of basic groups to form a series of flotation machines. During the flotation process, pulp will be mixed with chemical reagents and agitated. Then target ore grains will selectively attached to bubbles, float onto the surface of pulp, which will be scraped out and collected. ...
