Concentration of Ores: Hydraulic Washing, Froth Flotation ...

So nearly all rocks on the planet have some metal or mineral content. However, the concentration of this metal is too less for it to be valuable. Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of ores.

Introduction to Mineral Processing - cpchem.com

A collector is a chemical that attaches to the mineral surface and produces a hydrophobic (water-fearing) surface. While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used. This water-repellent film facilitates the attachment of the mineral particle to the air bubble.
