Bauxite and Barytes

In this line of minerals and ores, Bauxite is the most important aluminium ore. Barytes Mineral mainly consists of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH), and diaspore α-AlO(OH), along with the iron oxides goethite and hematite, the clay mineral kaolinite and small amounts of anatase TiO2. Barytes mineral has got name from the village Les Baux in southern France, where geologist Pierre Berthier had first discovered it in 1821.
The bauxite aluminium ore finds its application in diverse industry as a raw material for extraction and refinement of aluminum. The aluminum in bauxite exits in combination with different minerals which are gibbsite: Al(OH)3; boehmite: AlO (OH) and diaspore: AlOOH. We offer different grades of bauxite in large quantity for various industrial users across the world.
Barytes mineral (or barite) is the naturally occurring ore of barium sulphate. The main properties of barytes mineral include its high specific gravity (4.5), very low solubility, non-toxicity, and with that chemically and physically non-reactivity.

Applications areas:
Its application areas include
Oil industry (77%)
Chemicals (electronics, TV screen, glass, ceramics and medical applications: barium meals- 15%)
Fillers - car, rubber and paint industry, radiation shielding (8%)
Growing due to increase in LCD/plasma TV screens.
75% European domestic production for added-value sectors – overall the chemical and filler industries account for half of the barytes consumption.
Factors responsible for demand:
In the USA over 90% is for the oil industry.
China is 50% of world production; with India, USA, Morocco and Mexico a further 30%.

Features:
Barytes is an environmentally friendly material as it is a natural product and not a synthetic one and it is also not subject to registration under the new EU REACH regulations. Substitution potential is there but the alternates in the oil industry (e.g. ilmenite, haematite) are economically not a good deal. Cheaper alternate ground limestone or clays are sometimes used on economy grounds in some filler applications where quality or technical considerations are less stringent.
Salient feature include
Natural Product
Non Toxic
Inexpensive
Inert - Chemically and physically non-reactive to eco-systems
High specific Gravity
Good sound-deadening and radiation-shielding
Low oil adsorption
