Zircon is Zirconium Silicate (ZrSiO4). Mineral produced at various mineral separation plants form specific grades in terms of ZrO2 content ranging from 64.5 % to about 65.5 % with SiO2 content of little over 32%.

Zircon is Zirconium Silicate (ZrSiO4). Mineral produced at various mineral separation plants form specific grades in terms of ZrO2 content ranging from 64.5 % to about 65.5 % with SiO2 content of little over 32%. Applications: Zircon is used for production of: * Zircon flour and opacifier that are used as coating in ceramics, sanitary ware, etc. to impart opacity to the end-products. * Special purpose refractories. * various zirconium compounds. * Zirconium metal which is used in Atomic reactors as moderator. It is also used in foundries for mould making and foundry paints to withstand high temperatures

Sillimanite is Alumino-sillicate mineral (Al2SiO5). Mineral produced at two mineral separation plants has guaranteed Al2O3 content of 58%.   Applications: Sillimanite is used: * in production of refractories that find usage in metal and alloy making industry * by ceramic and foundry industry

Rutile is a titanium bearing mineral (TiO2). The TiO2 content in rutile produced by all the three mineral separation plants is over 94%.   Applications: Rutile is used for production of: * Titanium dioxide pigment, used in paints, papers, plastics, textiles, etc. * Titanium sponge, that finds application in aircraft body, artificial limbs, golf clubs, etc. * Welding fluxes, used as coating on welding electrodes.

Rare Earths or Lanthanides are a group of 17 elements from Lanthanum to Lutetium (15) plus Yttrium and Scandium. The following high pure rare earth compounds are being produced at Rare Earths Division in Kerala:

Ilmenite is a titaniferrous mineral (FeTiO3). Mineral produced at various mineral separation plants form specific grades in terms of TiO2 content ranging from 50 % to about 60%. The FeO and Fe2O3 content also varies between 10 ~ 20 % and 12 ~ 27 % respectively.

Garnets are silicate group of minerals. Garnet produced at two mineral separation plants is Almandine Garnet [Fe3Al2(SiO4)3]. Major grades produced are Coarse grade (30 - 60 mesh), Normal grade (60 - 100 mesh) and Medium grade (50 -  100 mesh)   Applications: Garnet is used: * as abrasive for sand blasting for descaling of vessels and surface preparation. * in water jet cutting for precision cutting job. * as abrasive in grinding wheels. * as medium for water filteration * for rough glass polishing
