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.
Â
Â
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.Â
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
