  • Talc Mineral Production Formation of Talc Golcha Minerals

    Talc formed through Dolomite: When alteration is done on magnesium carbonate rocks like magnesite and dolomite that are of sedimentary nature at high temperature then the talc is produced. For this, the pressure should be less than earth’s surface. The hot fluid which contains the silica transports it which then reacts with the magnesium and results in the formation of talc. The resultant
