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 finely grinding the ore to liberate valuable particles in a host rock, and may be followed by metallurgical processes.
