Talc H2Mg3(SiO3)4
Talc, also known as talcum powder, is a naturally occurring clay mineral.
Its chemical makeup is hydrated magnesium silicate, with the formula H₂Mg₃(SiO₃)₄ or Mg₃Si₄O₁₀(OH)₂.
Found in loose form, talc is a major ingredient in baby powder, often mixed with corn starch for added absorbency.
Talc typically occurs in flat, sheet-like formations (foliated) or fibrous masses, with a very rare crystalline form.
Interestingly, it has a property called perfect basal cleavage, meaning it can break cleanly along a specific plane.
Talc Productions
Talc Composition:
The passage confirms that the main component of this talc is hydrated magnesium silicate, which is consistent with the general definition of talc.
Talc Deposit Shape:
The talc is found in lens or vein formations within the rock, particularly concentrated in the lower and upper basal sections. This indicates a layered or stratified deposit.
Talc Deposit Dimensions:
The raw talc bodies are described as being quite large, with heights reaching 80 meters and widths of 50 meters. Thickness varies between 5 and 20 meters.
Talc Deposit Reserves:
The estimated reserve of this talc deposit is a substantial 365,000 tons.

Uses of Talc: Talc has various industrial and consumer applications. I can provide details on these.
The passage accurately describes talc’s versatility, being used in a wide range of products like paints, paper, pottery, and cosmetics.
It’s also used in industrial applications like rubber manufacturing and as a lubricant.
Important Note on Asbestos:
Health Concerns:
It’s crucial to mention that talc can sometimes be contaminated with asbestos, a known carcinogen.
Inhaling asbestos fibers can lead to serious health problems, including lung cancer.
Regulations:
Due to these health risks, the use of talc containing asbestos has been banned or heavily restricted in many countries.
Safer Alternatives:
Thankfully, safer alternatives to talc containing asbestos are available for most applications.
