Talc is our planet's softest known mineral. All talcs are lamellar, chemically inert, organophilic and water repellent, but no two talcs are the same. Their unique properties bring added performance to a wide range of products and processes.
 
 
Talc is also called steatite or, in chemical terms, hydrated magnesium silicate. It is the main component of soapstone. Its crystals usually develop massive, leafy aggregates with laminar particles. 
There are many types of talc and each ore body has its own features, . As a natural ore, talc is always found in combination with at least one other mineral.Although all talcs are lamellar, their platelet size differs from one deposit to another. Small crystals provide a compact, dense ore, known as microcrystalline talc. Large crystals come in papery layers. This form of talc is known as macrocrystalline talc.People always think of talc as white, but it can also be grey, green, blue, pink and even black.
The major applications for talc are plastics, paper, ceramics, paints and coatings, rubber, food, cosmetics, pharmaceuticals,
Current annual world talc production stands at around 5.5 million tonnes, mined from about **0 deposits scattered across the globe. The term 'talc' covers over **0 products, each distinct by its nature, by the proportion of by-minerals it contains, and by its properties.
China is the leading talc supplier with annual output 2 million tonnes. Majority of pure and white talc are from China
