flotation cell parameters

Flotation Cell Control - International Mining

flotation circuit. Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) 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. Each of the flotation cell control parameters are discussed ...
