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 "ed" with the assistance of specific chemicals, water and air bubbles.


Froth Flotation and Gold Extraction - Manhattan Gold & Silver

In gold mining, froth flotation is used to separate gold from gangue by utilizing gold's hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the ...
