Beneficiation of fine Weipa bauxite tailing

Two types of Bauxite are mined in Weipa, Northern Queensland, and are  designated as Andoom and Weipa ores depending on the deposit. To improve the grade of these ores washing is usually done which results in a lot of the constituent siliceous material being washed away. The resultant bauxite product then achieves a grade of about 60% …

Uses of Bauxite

Bauxite ore is soft and red clay, rich in alumina, and its name originates from Les Baux de Provence, It was French geologist Pierre Berthier who first discovered bauxite near a village in southern France in 1821. Later, a French chemist named Henri Sainte-Claire Deville officially termed the substance "bauxite" in 1861.

Bauxite deposits in Suriname: Geological context and resource

This bauxite deposit, with an overburden of approximately 40 m, was discovered in June 1959 during reconnaissance core drilling along the Coermotibo River, but was neglected due to its high sulfide content and resilication (Bárdossy & Aleva, 1990) despite a high average Al content (51%) and a low average Fe 2 O 3 content (4%).

Mineralogical and Geochemical Characteristics of the Sangarédi Bauxite

The mineralogical analyses show that gibbsite and boehmite are the dominant minerals in all of the bauxites, with average concentrations of 91.85% and 3.3%, respectively. Goethite is the major iron mineral, with an average concentration of 1.35%. whereas hematite makes up average of 0.7%.

Bauxite: The principal ore of aluminum.

Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale. It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.

Bauxite: The aluminum mineral bauxite information and pictures
