  • 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.

    Control of product ash in mechanical flotation cells is another important aspect in CHPP operation, with product ash generally increasing down a flotation bank. The primary reason for the increase in ash content down the bank is probably due to the lack of attention to froth stability in coal flotation cell
