Flotation Circuit - an overview | ScienceDirect Topics

Froth flotation design and operation are complex tasks because various important parameters are interconnected. The parameters can be classified into four types of components, as shown in Fig. 1 If any of these factors is changed, other parts of the design will also be changed. It is impossible to study all of the parameters at the same time.

Mineral Flotation - International Mining

Changing one thing in the circuit seemed to improve something but always got a negative response in some other variable. It was also very hard to measure the performance of the flotation circuit because the only real parameters you could measure on line were concentrate grades and tails of the circuits, which were always after the fact.

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.
