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.

Handbook of Flotation Reagents | ScienceDirect

In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore. Selectivity between chalcopyrite and sphalerite, in principle, is determined by the type of copper minerals present in the ore.

Modified Fatty Acids: Molecular Modeling and Docking ...

Fatty acids are known as oxhydryl collectors which are used in practice for non-sulfide ore flotation. However, the selectivity of these collectors is low towards to gangue minerals occurring in the ore. In the present study the introduction of substitutes into the aliphatic chain of fatty acids has been suggested as the way for improvement the selectivity of collectors.

Recovery of Gold in Pyritic Sulfide Ores - mine-engineer

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.
