Page 17 - Aluminium monohydrate, possibly in the form of the mineral boehmite, sometimes occurs in appreciable amounts in the red bauxite but is comparatively rare in the yellow bauxite. The silica is present mainly as disseminated clay minerals, the titania probably as hydrated oxides, and the phosphorus very likely as iron phosphate.1 The advantages of the comparatively low silica content ...

The bauxite deposits in parts of south-central Jamaica are hematite-rich, have low phosphorus and are traditionally processed in a low temperature alumina refinery. Supplies of these resources are diminishing however and new bauxite feed is expected to come from the goethite-rich, high phosphorus deposits that are located north of the current ...

Tabulated data show the U content in ppm, Ra in ppm equivalent U, Th in ppm, K, and Th/K ratio. The significant detail revealed is that during bauxite formation potassium was extensively depleted, Th accumulated, and U remained unchanged, resulting in a Th/K ratio tens and hundreds of times greater in the bauxite than in the country rock.

Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.Bauxite does not make aesthetic or interesting specimens as far as collectors are concerned, but it holds importance as being the primary ore of ...

Bauxite Mining's Negative Effects on Human and Environment. Bauxite dust is produced in bauxite mining, resulting in air, water, and soil pollutions. The immersion of bauxite in water leads to a decrease in soil fertility and affects the sources of agricultural products and aquatic organisms.
This is the first time in the history of Jamaica, as far as I am aware, that this information will be presented in this fashion. I have written that it has been a travesty of justice that the Jamaican government does not own at least 100,000 shares of Alcoa stock. Alcoa has been mining our bauxite for 40 years and we own not even a single share!
