Effect of pH on the Recovery and Grade of Base Metal

One of the most important aspects of froth flotation is the formation of a froth in which the valuable minerals are retained for further up grading Thus the presence of a surface active or frothing agent either as a neutral frother or in the dual function as collector and frother is vital to the process 8 When mineral surfaces have been made

Entrainment of Gangue Minerals in Froth Flotation

31 08 2020  Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp and eventually discharge to the concentrate product even when they are not attached to gas bubbles Therefore entrainment can be considered as a two step process one at the upper layer of the pulp to the flotation froth and the other from froth
