Aluminium life cycle. The main raw material for aluminium production is bauxite. Aluminium oxide is extracted from the bauxite, and is used in an electrolytic reduction process to produce primary aluminium. It takes roughly 47 metric tons of bauxite to produce 2 metric tons of alumina, which then yields 1 metric ton of aluminium.

How Gold Works. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the goldbearing carbon.
In addition to alumina, bauxite itself is used as a refractory material, in Portland cement, abrasives, mineral fibres, steel and calcium aluminate cements.
In an alumina refinery bauxite is processed into pure aluminium oxide (alumina, or Al 2 O 3), which is the main raw material required for production of primary aluminium. The Bayer process extracts alumina by caustic digestion of crushed bauxite at high temperature and pressure in an autoclave, followed by clarification, precipitation, washing and finally calcination to produce pure anhydrous alumina.
