Talc

Talc, H2Mg3 (SiO3) 4 or Mg3Si4O10 (OH) 2. It is a mineral consisting of hydrated magnesium silica with a chemical formula. Mohs is the softest mineral known by its hardness value. Talc can be prevalent as crystals, which are generally monolithic, rarely macroscopically detectable.Since the begining of the production ,Tecnodieci minning adds new products to its portfolio,to compenste the need of very fine and white Talc for paper,rubber,plastic,ceramic,paint,and food industries,tecnodieci produce on many different quality,any particle size and different witness
