30 bauxite and alumina usgsbauxite and alumina in april, the government of malaysia ended its ban on bauxite mining that was imposed in january because of concerns about pollution from mines and uncovered stockpiles at ports. during the mining ban, exports of stockpiled bauxite were allowed and media sources reported that some mines continued illegal mining.alcoa bauxitealcoa has ownership in seven active bauxite mines globally and operates four of them, making us among the largest bauxite producers in the world. we have access to large bauxite deposits with mining rights that extend in most cases more than s. our global network is strategically located near key atlantic and pacific markets.mining and refining process world aluminiumonce 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 mines. unlike the base metal ores, bauxite does not require complexmining and refining process world aluminiumtwo to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.how aluminium is producedthe world's largest bauxite producers, the most common way to mine for bauxites is by using open pit mines. special equipment is used to cut one layer after another off the surface, with the rock then being transported elsewhere for further processing.australia rio tintoin the pilbara region of western australia, we own an integrated portfolio of iron ore assets a worldclass, integrated network of mines. our weipa operations in far north queensland includes three bauxite mines, processing facilities, shiploaders, an export wharf, two ports, power stations, a rail network and ferry terminals. read more .
