The Extraction of Copper
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico. from Rob Lavinsky (iRocks) under a CC-BY-SA-3.0 license.

Aluminium Metallurgy
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 …
