  • Dynamic Modeling and RealTime Monitoring of Froth Flotation

    In typical froth flotation operations, large variations in the feed composition and various disturbances affecting the system result in a decrease in the grade and recovery. Control strategies applied to flotation systems typically target bias, froth depth, and gas hold up using feedback control by manipulating variables such as air and water flow rates, and reagent addition [ 2, 3, 4 ].

    The performance of the froth phase, usually evaluated as froth recovery determines overall flotation performance. In most flotation operations, recovery across the froth is rate controlling; consequently understanding the froth phase is very critical. Although much research effort to understand the physics of the froth has been expended, not
