bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process with less than 1.5 kilograms of fuel oil and less than kwh of electricity consumed per tonne of bauxite extracted.jun 18, 2010 the normal production route taken is to refine the bauxite to aluminium oxide, or alumina which is a white, crystalline powder. this powder is then smelted to form aluminium metal. As a general rule, four tonnes of dried bauxite is required to produce two tonnes of alumina, which in turn provides one tonne of primary aluminium metal.


jamalco mines bauxite and refines it into alumina before it is exported from its port at rocky point, clarendon. On average, 2.5 tonnes of bauxite produce one tonne of alumina. the alumina is exported to aluminium smelters where it takes around two tonnes of alumina primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of to percent alumina and lesser amounts of iron, silicon, and titanium. the ore is refined into alumina by the bayer process. the alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.
