Hydroxamates For Froth Flotation

Frothers Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process Reduce surface tension of the liquid gas interface to enable froth formation Hinder coalescence in order to stabilize bubble size.
