Bauxite is the only raw material used in the production of alumina on a commercial scale in the United States. However, the vast U.S. and global resources of clay are technically feasible sources of alumina.
At a $10.00 bauxite price, and using the Bayer process, bauxite represents about 26% of the cost of producing alumina (see Table 4). At a bauxite price of $20.00, bauxite represents 40% of the cost of producing alumina. In fact only about 88% of bauxite and alumina consumed in the U.S. is used to
The decreased in the production of bauxite in Jamaica were followed by job loss. Now Jamaica bauxite which was once the world largest bauxite producer started to loose it's market to other countries. In addition to other countries producing more bauxite, the global prices for ore dropped.
Bauxite price slowly climbing, with tight global supply and high demand from Chinese alumina refineries
Raw, uncalcined bauxite is used for cement, slag conditioning, and chemicals. Calcined bauxite is produced to make abrasive, refractory, welding, and proppant grades. Abrasive grade bauxite is fused to manufacture brown fused alumina used in abrasives and refractories.
Primary production starts with bauxite ore, which, in the United States, is usually imported from Jamaica and South America. Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States.
The bulk of world bauxite production (approximately 85%) is used as feed for the manufacture of alumina via a wet chemical caustic leach method commonly known as the Bayer process.
Bauxite is the most common raw material used to produce alumina for aluminium metal production. Bauxite deposits are mainly found in a wide belt around the equator. Hydro's bauxite mines are located in the state of Pará, in the northernmost part of Brazil.
