3H 2 O. The exact composition of talc depends on the location of mining, since talc from different mining locations may contain significantly different proportions of MgO, SiO 2, and H 2 O. Talc has a layered platey. Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and.
Talc is basically a mineral which belongs to the class of silicates. The formation of talc is achieved when the carbonate sediments undergo through contact is also formed when the magmatic rocks which are rich in magnesium undergoes the hydrothermal rocks which contain talc are metamorphic in nature and therefore talc is produced as secondary mineral.
These metamorphic rocks crop out in mountain belts such as the Alps, the Appalachians and the Himalayas and in ancient continental shields such as the Canadian shield in New York and Canada.
The occurrence of talc deposits of commercial importance is described extensively in Section The talc used by this cosmetic company that manufactured and distributed the talcum powder was from three distinct regions: the Willow Creek mine in Southwest Montana, the Regal mine near Murphy, North Carolina, and imported talc from the Val Chisone region of the Italian Piedmont.

The talc deposits mined in southwestern Montana produce some of the purest talc in the world (Van Gosen et al., ).Many of the Montana talc products are of the compact or microcrystalline variety and are in great demand for manufacturing paper, paints and coatings, plastics, rubber, ceramics, and agricultural products.
of talc. Talc is also used as a term to describe a rock that contains the mineral talc. Other names for talc-rich rocks are steatite, a high-purity massive variety, and soapstone, an impure rock containing talc and other minerals. Geology of U.S.
Talc Deposits Significant United States talc deposits occur in. All four talc deposits occur within the Shadli metavolcanic rocks of the Hamamid Group, which consist of mafic, intermediate and felsic volcanics and pyroclastics (Fasfous, ).

The name talc The name talc is believed to be derived from the Arabic word talc or tolk meaning mica, since talc forms mica-like flames. The present name was given by Georgius Agricola in Talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness.
Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rock-forming minerals. Dense aggregates of high-purity talc are called steatite.

Talc itself is a naturally-occurring mineral composed of hydrated magnesium silicate.2 It’s mined from underground deposits and used in hundreds of products across many industries. Most people. Talcum powder is made from talc, a mineral made up mainly of the elements magnesium, silicon, and oxygen.
As a powder, it absorbs moisture well and helps cut down on friction, making it useful for keeping skin dry and helping to prevent rashes. It is widely used in cosmetic products such as baby powder and adult body and facial powders, as well. A relatively new use is in water clarification, where finely ground talc increases the sedimentation rate of fine particles.
Talc is a constituent of soapstone, which is used in sculptures. There are 3 talc mines in Canada, 1 in Québec and 2 in Ontario. Canada's annual production is about 80 t. O Canada!
