Talc ores also differ according to their mineralogical composition (i.e. the type and proportion of associated minerals present). They can be divided into two main types of deposits: talc-chlorite and talc-carbonate. Talc-chlorite ore bodies consist mainly of talc (sometimes ) and chlorite, which is hydrated magnesium and aluminium silicate.

Talc formation and deposition: The formation of talc occurs in separate geological environments. The talc deposits are different from each other on the basis of current composition and also on the parent rock composition from which it is derived. The talc deposits can be categorized into four types.
Talc is one of the most versatile and useful industrial minerals. It is a hydrous magnesium silicate (Mg 3 Si 4 O 10 (OH) 2), the massive variety of which is known as steatite or soapstone.Talc is soft (1 on the Mohs scale of hardness), non-abrasive, inert and easily ground to a fine white powder used in many applications including:
Talc is a hydrated magnesium silicate. There are many types of talc and each ore body has its own features, its own geology, formed many millions of years ago. As a natural ore, talc is always found in combination with at least one other mineral. The most common of these is chlorite, a chemically and structurally similar ore.
Mining in is underdeveloped, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of .
Talcum powder (also known as baby powder) is made of talc, a mineral consisting of magnesium, silicon, and oxygen. Talc is obtained through mining mineral deposits, which are often inter-mingled with deposits of a type of asbestos known as asbestiform tremolite.Asbestos is most dangerous when it is friable, meaning that it is powdery or crumbles easily, producing tiny inhalable fibers.
The story of why Natural Minerals talc is superior goes back 3,000,000 years.
