Best Answer

At the extraction mill, bauxite ore is crushed and dissolved in sodium hydroxide (caustic soda). The solution travels through a series of filters and separators to remove the insoluble particles, leaving the liquefied sodium aluminate.As the alumina settles to the bottom, the caustic soda is pumped off and reused. The clumps of pure alumina are dried and ground to a fine white powder. The powdered alumina can be refined into metallic aluminum or used in different manufacturing processes.

Is aluminium extracted by heating their oxides with carbon?

No, it cannot be extracted this way as aluminium is a much stronger reducing agent than carbon and has greater affinity to oxygen. It is rather extracted by the process of electrolysis by passing electricity through molten aluminum ore which is bauxite mixed with cryolite.
