Flotation Oils for Froth Flotation | ArrMaz

Flotation oils act as co-collectors, extending the collector's ability to float the desired mineral. They provide strength to the hydrophobic layer. The amount and type of flotation oil used can directly impact the nature of the froth, and thus can control the strength and selectivity of the froth zone.

Mineral - Classification of minerals | Britannica

Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
