2017-10-27One of the key steps in the flotation method is the introduction of air bubbles into water. In early flotation machines, coarse bubbles 2 to 5 mm were introduced into the contaminated water by blowing air through canvas or other porous material. In some impeller-based machines, air could be introduced from the atmosphere without.Get A Quote

2020-1-20A mayor constraint on column flotation capacity is froth overloading. The carrying capacity of the froth depends on the bubble surface area available for bubble-particle attachment. The bubble surface area, and hence carrying capacity, can be increased by reducing the average size of bubbles for a given gas flow rate. Efficient and proper air.Get A Quote
