Flotation Cell Control - International Mining

2005-9-15 · 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.
