When Mining Bauxite Ore

The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers. Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to

    Bauxite Mining | The Australian Aluminium Council

    Bauxite Mining. Aluminium is the most abundant metal in the Earth’s crust, occurring as bauxite which contains aluminium oxide. The first step in producing aluminium is mining this ore. Bauxite occurs mainly in tropical and sub-tropical areas, like Africa, the Caribbean, South America and Australia. Australia is the largest producer of bauxite, with five large mines supplying around 30 per cent of
