The ore usually contains less than 1% copper and is often associated with sulfide minerals. The ore is ground, concentrated, and slurried with water and chemical reagents. Air blown through the mixture attaches to the copper, causing it to float to the top of the slurry.

Process Description24 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.

The copper can be sold to wirerod mills or further processed into rods. Anode slime refers to impurities that sink to the bottom of the electrolytic cell. The second method for refining copper is called the hydrometallurgical process. This process begins with oxidized copper ores or oxidized copper wastes.
