By the end of the 1700s, aluminium oxide was known to contain a metal, but it defeated all attempts to extract it. Humphry Davy had used electric current to extract sodium and potassium from their so-called ‘earths’ (oxides), but his method did not release aluminium in the same way.
Aluminum occurs in igneous rocks chiefly bey aluminosilicates in feldspars, feldspathoids, and micas; in the soil derived from them bey clay; and upon further weathering bey bauxite and iron-rich laterite. Bauxite, a mixture of hydrated aluminum oxides, is the principal aluminum ore.
