Kaynite

Kaynite Mines are presently operating two semi–mechanized mines which produce kyanite and sillimanite in the Ramgarh Cantt -829 117 district Rangarh (in the Jharkhand). We have also set up Ore dressing and grinding unit at Village Orla, Distt : Rangarh, where in we are producing kyanite/Sillianite concentrate along with powder and grains of various sizes ranging from 100 to 325 mesh and grains of 3/5 to 1/0.5 mm.

Kyanite Powder

Kyanite is a member of the Sillimanite group of minerals. This Mineralogical group includes Kyanite, Andulusite and Sillimanite - all of which are naturally occurring polymorphs of Al2o3.Sio2. These are commonly referred to as the 1:1 Aluminop-Sllicates.

Raw Kyanite is a Blue crystal, Subhedral in shape and occurs in Elongated Prismatic grains. Kyanite has the property of expanding irreversibly when heated. The degree of volume expansion is dependent upon mesh size of the Kyanite. This expansion helps in offsetting the shrinkage of other raw material and binders employed in the mix and this makes it an important ingredient in the manufacture of refractory.

Kaynite Specification :

Kyanite, whose name was derived from the Greek word Kyanos which means Blue. It is typically blue silicate mineral, commonly found in Aluminum - Rich Metamorphic Pegmatite or Sedimentary Rocks. Kyanite is a member of the Aluminosilicate series, which includes the Polymorph Andalusite and the Polymorph Sillimanite. It is strongly Anisotropic, in that its hardness varies depending on its Crystallographic direction. While this is a feature of all most all minerals, in Kyanite this Anisotropism can be considered an identifying characteristic.
