Global Mass Balance of Bauxite Production Chain | E & MJ
Bauxite ore is the basic raw material for the aluminum production chain, which has four major steps, normally implemented as separate industrial plants: processing of the raw ore from bauxite mines to produce concentrated ore with specific quality requirements; refining of the concentrated bauxite ore through the Bayer process to produce high-purity smelter-grade alumina; electrolytic

Environmental Guidelines for Aluminum Manufacturing
bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing, size classification, liquid/solid separation) to remove unwanted materials such as clay and silica. At the alumina plant the bauxite ore is

Copper extraction
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena.
