Bauxite, Feature : Accurate Composition, Highly Effective

Bauxite Mixture of Iron and Aluminium Hydroxides/Oxides
Al, Fe, O, OH
Bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade or can be improved by a relatively simple and inexpensive process of removing clay.
The History Says
The first aluminum made in the US. was mined in Bartow and Floyd counties by the present Aluminum Company of America. A local man, Mr. Gibbons, operated these mines and also deposits in Arkansas, where the town near the deposits was named for him. He became a top official of Alcoa. The American Cyanamid Company mined bauxite to make alum. Large foreign deposits caused local mining to cease.
The Present Scenario
Exporting bauxite mines generated about US$1.4m in revenue per hectare mined in 1998 and a typical mine employed about 200 people for each million tonnes/year of bauxite produced or about 11 people per hectare.
