SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Self aspirated flotation machines have historically been favored in low technology processing plants, as air addition is one less variable that must be controlled. However with most modern plants having computer based control systems, the ability to accurately control the air addition rate in to the flotation cell gives the operator a

Flotation Feed an overview ScienceDirect Topics

Modern simple plants, which gravity feed flotation concentrate directly from the flotation cell launder onto filters, usually do not provide sufficient shear for floc mixing, or residence time for floc formation. This is believed to lead to over flocculation. 13.3.2 Fractional dewatering approach and coarse addition

Flotation Cell Control International Mining

flotation circuit. Flotation cells have three main control parameters reagent dosing rate froth depth and air addition rate. Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself.
