Recycling aluminium. About 39% of the aluminium in foil, car components etc. is recycled aluminium. This makes good economics because recycling saves on costs AND allows a mineral resource like aluminium's bauxite ore to last a lot longer – slower depletion of the Earth's mineral ore resources will make it last longer.
Aluminum is the most abundant metal element in the earth's crust, but it is always found in a compound rather than an easilyrefined ore. Alum is one such compound. Scientists tried to tease the metal out of alum, but the process was costly until Charles Martin Hall patented an inexpensive method to produce aluminum in 1889.

Mar 04, 2015· Bauxite, the main ore of aluminum, contains about 5060% alumina (aluminum oxide, Al 2 O 3) and is formed by the weathering of aluminumrich rocks under tropical conditions. Aluminum is produced by separating pure alumina from bauxite in a refinery, then treating the alumina by electrolysis.
Manufacture of copper. About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only about % copper.
Quick Read. Primary production is the process by which alumina is smelted to pure aluminum metal. The Hall–Héroult process, simultaneously discovered in 1886 by American Charles Martin Hall and Frenchman Paul Héroult, continues as the main industrial process by which primary aluminum is made.
