Aluminium production breakthrough-1886 when Charles Martin Hall in Ohio and Paul L. T . Heroult of Paris independently applied for patents for the electrolytic process in molten salt for manufacturing aluminum. Both electrolyzed alumina (aluminum oxide) dissolved in molten Greenland cryolite (sodium-aluminum fluoride Na3AlF6) at about 1000oC (1832oF).

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of the metal aluminum. Bauxite is named after the French village of Les Baux, where it was first recognized as an aluminum ore .

In the bauxite refining process, the aluminum-bearing minerals in bauxite are converted in a multiple-step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high-temperature rotary kilns and metallurgical furnaces.
