Copper processing
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace …

Copper Metallurgy
The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.

In addition, copper and iron were obtained 28.26% and 27.92%, respectively, for a 15% solid-to-liquid ratio. However, copper and iron were obtained 25.72% and 27.4%, respectively, for a 20% solid-to-liquid ratio. The extraction of copper increases up to 10% of the solid-to-liquid ratio; after that, it will show a decreasing trend.

An Introduction to the Chemistry of Metal Extraction
Instead, the usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.
