Unlike other base metal ores bauxite ore does not require complex extraction processing because most of the mined bauxite is of an acceptable grade or can be improved beneficiated by a relatively simple but not inexpensive process of removing clay

An overview of this conversion process and the materials along the way are described here Bauxite Aluminum starts out as bauxite ore – an aluminum ore formed from laterite soil Bauxite is the world’s primary source of aluminum Before it can become aluminum however bauxite destined for use as aluminum must first be processed into alumina

Proven economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand While demand for bauxite is expected to grow as demand for high quality aluminium products increases new reserves will be discovered or become economically viable

One large alumina plant employing this modified Bayer Process has two parallel grinding and digestion circuits similar to that shown in this flowsheet The feed rate to each 7 ft diameter by 12 ft long rod mill is approximately 95 tons per hour of bauxite ore

The production of the metal Aluminum from the raw ore of Bauxite is a two stage process Stage 1 Converting Bauxite to Alumina The grinding mill rotates like a huge drum while steel rods rolling around loose inside the mill grind the ore to an even finer consistency
