analysis of bauxite Information on process parameters would allow better understanding of bauxite economical value and more efficient control of a Bayer plant.

Plant Location As illustrated by Figure 1, two bauxite refineries are located near the domestic bauxite deposits in Arkansas. The rest of those in the continental United States use imported bauxite and are located in the South.

Over the last 20 years, spontaneous plant colonization on the deposits has revealed that natural weathering processes may improve bauxite residue to the extent that it can support vegetation. Bauxite residue samples were collected from a chronosequence and analyzed to determine the effect of natural processes over time.

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite.

Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.

Bauxite is the main raw material used in the commercial production of alumina (Al 2 O 3) and aluminium metal, although some clays and other materials can be utilised to produce alumina. Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium.

1n 1917, bauxite mining started at Maria Elizabeth3 and nearby Akyma. Both areas are south of Mackenzie, about 8 miles upriver from the city. The area was briefly called Mackenzie City but the City was dropped later. The bauxite plant on the east bank of the Demerara River was soon built. The mining community would soon follow.
