Flotation Cell Control - International Mining

2021-3-18  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.

Expert system for supervision of mineral flotation cells ...

Abstract: This paper describes an expert system for the supervision of flotation plants that uses ACEFLOT, a real-time analyzer of the dynamic characteristics of flotation froth. The ACEFLOT analyzer, based on image processing, measures several physical parameters of the froth that forms on the cell surface. The expert system detects abnormal operation and suggests corrective actions ...
