Molybdenum Ore Processing by Flotation
This reagent depresses the copper sulphides. The conditioned sulphide pulp is then treated in a "Sub-A" cell-to-cell Flotation Machine for the initial molybdenum up-grading steps. These cells are usually the same size as the preceding copper cleaner cells as the entire tonnage of concentrates must be handled at this point.

Gold Carbon-in-pulp(CIP) Process
Gold carbon-in-pulp (CIP) is a typical gold beneficiation process for the effective recovery of gold-bearing minerals with a high oxidation degree and low grade of raw ore. Gold CIP has become a widely used gold extraction method worldwide because of its advantages of high adsorption rate, high recovery rate, and low investment cost.

Flotation
The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.

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 ...
