Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue.

In its simplest form, froth flotation is a method whereby minerals can be skimmed from the surface of slurry that is foamed with the assistance of specific chemicals, water and air bubbles.

ESTEC provides a wide range of formulations consisting of alcohols, alcohol ethoxylates, glycol ethers to provide the best performance based on the needs of each circuit.

Our specially designed blends have shown excellent selectivity, forming dry but easy-to-break froths – increasing both the yield and the efficiency of mineral and metal recovery efforts.
