Copper extraction requires liberation of these minerals from the host rock by fine grinding, during which rapid oxidation could alter their surface characteristics, thereby affecting their flotation behaviour.
Introduction to Mineral Processing - Chevron Phillips Chemical
The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.
12.3 Primary Copper Smelting
Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
