10-07-2021· 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.
Extracting a metal from its ore - chymist. that contain sufficient metal to be of practical and economic use are called or Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis
