Flotation an overview ScienceDirect Topics

Flotation is widely used to separate valuable minerals from the rock and fine coal particles from clay, silt, shale and other ash-producing matter. It is usually preceded by crushing and grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.

Flotation. Background. Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.
