TALC
Talc is a versatile mineral, widely used in various industrial applications. The nature of deposit, formation of talc is the index of its chemical purity, particle shape and other physical features. Talc possesses some unique and unusual properties, which makes it ideal for its multiple uses. No other mineral other than talc possesses such combination of intrinsic properties.
Mainly there are three types of structures in the talc Platy, Acicular and Granular. Minerals commonly associated with some commercial talc in significant amounts include the Carbonates, Calcite, Dolomite, Magnesite & other Silicates, Anthophyllite, Chlorite, Quartz, Serpentine and Tremolites. Serpentine and Tremolites are hazardous impurities possessing ACICULAR structure.
The deposits located in the north of Rajasthan, are in massive form of the talc, primarily with the Platy particle shape with high chemical purity and reflectance values. They are non-abrasive and free from ASBESTOS and BIMINERALS, especially grits etc.
The important properties of Talc are its chemical inertness, high dielectric strength, high thermal conductivity, low electrical conductivity and Oil & Grease absorption.

Talc
Magnesium silicate
The term talc refers both to the pure mineral and a wide variety of soft, talc-containing rocks that are mined and utilized for a variety of applications. Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).
Uses
Ground talc is used as an ingredient in ceramics, paper, paint, roofing, plastics, cosmetics, talcum and baby powders, and a variety of other assorted uses such as making rubber and plastics.
