Improving flotation energy efficiency by optimizing cell …
Energy consumption is a key parameter in all of these approaches. Specific power, the power used per unit volume of a flotation cell (kW/m 3), is commonly used to define the energy consumption of mechanical flotation cells and has been used as a scale-up criteria (Harris, 1975). It has also been correlated with flotation kinetics …

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 ...

CFD model of a self-aerating flotation cell
The results confirm current practice in many mineral plants where the feed streams are sized into coarse, fines and slimes and treated separately in customised flotation cells where the speeds are adjusted to suit the particle size. For practical application, the CFD model can be used to investigate performance of a flotation cell.
