Asbestos Mineral

Asbestos Mineral

Our clients can avail from us a wide range of Asbestos which is a mineral known for its toxicity along with thin fibrous crystals. Besides, t is made up of bundles of fibers which cant become airborne materials comprising asbestos is damaged. These fibers can get into air as well as also can cause some serious health problems such as lung cancer and others. Many countries have prohibited its use and import and the name is provided to a unique group fibrous minerals which may occur in many parts of world.

 

There are various kinds of asbestos but in commerce this term is only restricted to the following :

  • Chrysotile, which is a hydrous magnesium silicate
  • The amphibole group of asbesti form minerals which include:
  • Tremolite, a double silicate of calcium and magnesium
  • Anthophyllite, a silicate of iron and magnesium
  • Crocidolite or blue asbestos is a sodium iron silicate
  • Amosite (belonging to the cummingtonite-grunerite group)
  • Specific Gravity (Chrysotile) : 2.4 to 2.6
  • Specific Gravity (Tremolite) : 2.9 to 3.2

Barytes Mineral

Barytes Mineral

We hold expertise in offering a wide range of Barytes Mineral which consists of Barium Sulphate [BaSO4].and is known as Barite. It is characteristically dense & purer grades as well as also have specific gravity as high as 4.32 g.cm-3. It is white in color in its natural form but when contaminated it becomes red, grey or yellow. Further, it occurs in hydrothermal veins in limestones.

 

Uses:

  • As a weighting agent in drilling muds
  • As a pigment in paints
  • As a weighted filler for paper industry and cloth

 

These high density clays are circulated down the stem and after that return to the surface between the wall of the well and drill stem. This process flushes the cuttings that is generated by the drill and further carries them to the surface. The high density of this clay makes it opaque to X-rays and it is used to image the shape of organs by X-rays if it is given to patient as drink. Its name is originated from the 'Greek', Baryons and Heavy.
