In froth flotation, air is bubbled through an aqueous solution or slurry to which a ing agent (soap) has been added. The air-soap bubbles carry finely dispersed solids and hydrophobic materials such as grease and oil to the surface where they can be skimmed off in the , An ore-containing slurry is to be processed in a froth flotation tank at a rate of 400.0 tons/h.

Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and Cilliers, 2009, Hadler et al., 2012, Kowalczuk and Drzymala, 2017a, Kowalczuk and Drzymala, 2017). Although frothers improve flotation rate and recovery, a very high frother ...

Flotation with methanol did not produce the desired combination of high recovery and purity of products. A 40% methanol solution was required to depress ABS, which occurred at surface tensions below 40 mN m −1. No evidence to support the importance of solution density and pH in froth flotation behavior.
