Talcum is a non-metallic mineral resulting from the alteration of Magnesium Silicates. Talcum powder is generally obtained by washing and eliminating impurities on the stones and then crushing them mechanically. The resulting product is then ground to the desired particle size. Talcum is heat-resistant, insulating, resistant to acids and alkalis, resistant to corrosion. It is widely used in paper, paint, rubber, ceramic, pharmaceutical and chemical products
