Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The Guide of Flotation Defoamers - cnlitereagent.com

Flotation agents are chemical agents used in the mineral flotation process which can adjust the surface properties of the minerals, increase or decrease the floatability of the minerals, and make the pulp properties and foam stability more conducive to mineral separation. Common flotation agents are collectors, foaming agents, inhibitors, activators, dispersants, flocculants and defoamers.

Surfactants & Mine Dust Control & Effect on Flotation

Dust measurements in mines clearly indicated that the major mineral dust exposure is due to loading and transport of the ore from the mining areas. One approach to the solution of this dust problem is the application of water sprays to reduce dust dispersion. Wetting of broken rock is very effective in preventing fine dust from becoming airborne by binding it to the larger lumps. The ...
