Kyanite/Sillimanite so mined and processed by us is being catered to 90% of the refractory Industries in India, besides being exported to China. It is mainly used in refractory products like dense bricks, Insulating bricks, monolithic & castables. Certain quantities of Kyanite are being used in investment casting units and in foundries. Kyanite produced by PKM offers unique high temperature characteristics like high refractoriness, good expansion characterstics, mullite formation, improvement in RUL/Creep behavior and Low ferric content. It is free of tourmaline. |

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. |

Kaynite 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.
Kyanite is a super-duty refractory material with high resistance to thermal shock. It also decomposes into high strength phase mullite at a relatively low temperature 1350 - 1375 Deg.Celcius , there by inducing faster sintering. |

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.

Fire Clay
A good fireclay should have 24-26% plasticity and shrinkage after firing should be within 6-8% maximum. It should also not contain more than 25% Fe2O3.
The Present Scenario
Because of the abundant supply of fireclay and its comparative cheapness, the refractory bricks made out of it are the most common and extensively used in all places of heat generation. |

Industrial Applications
Because of the abundant supply of fireclay and its comparative cheapness, the refractory bricks made out of it are the most common and extensively used in all places of heat generation, like:
- Iin boiler furnaces
- Glass melting furnaces
- Chimney linings
- Pottery kilnsblast furnaces
- Reheating furnaces
Fireclay is classified under acid refractories. Acid refractories are those which are not attacked by acid slag. In blast furnaces, the lining is done almost entirely with fireclay bricks. Pouring refractories like sleeves, nozzles, stoppers and tuyers are made of fireclay.
Manufacturing Process
Manufacturing of refractory bricks from fire-clay is an interesting feature. The clay mined is stacked in the factory yard and allowed to weather for about a year. For daily production of different types of refractories, this weathered clay is taken and mixed in different percentages with grog.
The mixture is sent to the grinding mill from where it is transferred to the pug mill. In the pug mill a suitable proportion of water is added so as to give it proper plasticity. The mould is supplied to different machines for making standard bricks or shapes. Intricate shapes are made by hand. The bricks thus made are then dried in hot floor driers and after drying they are loaded in kilns for firing. The firing ranges are, of course, different for different grades of refractories. After firing, the kilns are allowed to cool; then the bricks are unloaded. By burning fireclay is converted into a stone-like material, highly resistant to acid, water and most other solutions. While manufacturing high aluminous fire-bricks bauxite is added along with grog in suitable proportions.

Bauxite
BAUXITE is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore. Bauxites are typically classified according to their intended commercial application: abrasive, cement, chemical, metallurgical, refractory, etc. The bulk of world bauxite production (approximately 85%) is used as feed for the manufacture of alumina via a wet chemical caustic leach method commonly known as the Bayer process. Subsequently, the majority of the resulting alumina produced from this refining process is in turn employed as the feedstock for the production of aluminum metal by the electrolytic reduction of alumina in a molten bath of natural or synthetic cryolite (Na3AlF6), the Hall-Héroult process. |
