BAUXITE

Bauxite is one of the most important industrial minerals and it being the aluminium ore, is the principal raw material for the production of alumina. Bauxite is also used as an important raw material for many other products like Alumina, Cement, Abrasives, High Strength Proppant, Emery, Alum etc. The Bauxite ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. There are two main types of Bauxite: the metallurgical and the non-metallurgical.

More than 160 million metric tons of bauxite are mined each year. The leaders in bauxite production include Australia, China, Brazil, India and Guinea. Bauxite reserves are estimated to be 55 to 75 billion metric tons, primarily spread across Africa (32 percent), Oceania (23 percent), South America and the Caribbean (21 percent) and Asia (18 percent).

Ametheus sources Bauxite directly from the largest miners in India, Jamaica, Turkey and West Africa. Best suitable for Aluminium smelters (metallurgical Bauxite) and Cement industries (non-metallurgical Bauxite).
