Abstract: Real Time State Estimation of Froth Flotation ...

This makes monitoring and control of the flotation process a difficult task. The main goal in froth flotation is to maximize grade and recovery of the desired mineral, while maintaining stable and upset-free operation (Fuerstenau, 2007). However, with highly varying feed properties and other related operating parameters, potentially leading to poor froth stability, which can result in reduced ...
