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.

Iron ore mining and dressing
Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.
