Worldwide bauxite mine production
To produce aluminum, bauxite is crushed and purified through the Bayer Process. It is a heavily energy intensive process and thus, is often produced in regions where energy costs are the lowest. Bauxite can also be used as an abrasive. Requiring the recycling of aluminum can lower the cost of electric power in aluminum production and also prolong the existence bauxite reserves. Nevertheless, reserves remain fairly high even at current production levels. Guinea has some the largest bauxite reserves in the world.
Australia, China, and Brazil are some of the most dominant countries in bauxite mine production, generating 81.1 million, 46 million, and 32.5 million metric tons of bauxite, respectively, in 2013. In the United States, revenue from aluminum manufacturing has decreased from 43.5 billion U.S. dollars in 2008 to 37 billion U.S. dollars in 2013. However, global demand for aluminum is expected to increase by 5.1 percent in 2015. China’s Chalco is one of the large producers of primary aluminum in the world, with an output of 3.8 million metric tons of aluminum in 2013. The Huntly mine in Australia is one of the largest producers of bauxite in the world; it is owned by Alcoa World Alumina. In 2012, the transportation and construction sector consisted of just over half of the global use of aluminum.
