Flotation Of Metallic Copper

Mineralsminerals Refining Company

The problem with flotation is that it becomes notoriously inefficient below 10 microns throwing away these fine particles is particularly counterproductive in that more liberation of ore particles can be expected at finer sizesa solution is in sight hhs hhs has no known lower particle size testing and previous projects have shown that hhs can efficiently capture particles that are less than a single
