1.1 Integrated Grinding/Flotation Optimization. To maximize the metal recovery and operating profit, the mill has to be operated at the optimal mill production target. Using data validation and classification algorithms enables an estimate of the rougher flotation metal recovery in real-time.
A stronger frother creates a thicker film and weaker frothers create a thinner film. As the film thickness changes, so does the water recovery to the froth. In this way a frother will create a stabilized by the presence of water; in flotation particles take on some of this role to create a stabilized froth (15).
