How to maximize ore and grade recovery through flotation
Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed. It is possible that some banks of flotation cells might not be recovering ore at their maximum levels due to air flow, feed, mechanical, hydraulic, reagent imbalances. Recognizing the need for a solution that ...
