The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the

Copper Ore - an overview | ScienceDirect Topics

The most effective method of isolating the Cu minerals is froth flotation. This process causes the Cu minerals to become selectively attached to air bubbles rising through a slurry of finely ground ore in water (Fig. 1.4).Selectivity of flotation is created by using reagents, which make Cu minerals water repellent while leaving waste minerals wetted.
