Then, the liquid shape of the aluminium that has sunk to the bottom. On the other side, at the positive anode, the oxygen from the aluminium oxide forms and responds to carbon dioxide CO2 with the graphite carbon.

Aluminium Extraction SlideShare

Aluminium: ores • It occurs as bauxite ore which is a form of aluminium oxide. • Because aluminium is so reactive carbon is unable to pull away the oxygen from it. • It is extracted by electrolysis of moltenmolten bauxite. Early attempts at this failed because bauxite is so hard to melt. • If cryolite is added, the bauxite melts more easily. This is an essential step in the extraction
