Bauxite Ore Electrolytic

Aluminium ore, most commonly bauxite, is plentiful and occurs mainly in tropical and sub tropical areas Africa, West Indies, South America and Australia with some deposits in Europe. Although plentiful, bauxite quality is diminishing, is often not readily accessible and is becoming harder to gain approvals for expansions or new mines.

2019 12 11The aluminium scrap, in a steel furnace lined by alumina bricks, is heated from outside the furnace with gas or oil burners. The molten aluminium is then run off and solidified as ingots. Aluminium can be repeatedly melted and re used. Recycling 1 kg of aluminium saves up to 8 kg of bauxite ore and 4 kg of other chemical products.

    Aluminium Mining Techniques Mines Occurence

    Bauxite is the only ore containing 20 25 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.
