Metallurgy is the process of extracting metals from ores. Mining is the most common method of extracting metals from the earth. Metals are mostly found in nature in a mixed condition, however, they can also be found in a free state. A native metal is one that can be found in its pure form or as part of an alloy in its natural state.

Introduction. Aluminum is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic. Instead, it is extracted by electrolysis. The ore is first converted into pure aluminum oxide by the Bayer Process, and this is then electrolyzed in solution in molten cryolite another aluminum compound.
