  • Talc Mineral Production - Formation of Talc | Golcha Minerals

    Talc is basically a mineral which belongs to the class of silicates. The formation of talc is achieved when the carbonate sediments undergo through contact metamorphosis.It is also formed when the magmatic rocks which are rich in magnesium undergoes the hydrothermal alteration.The rocks which contain talc are metamorphic in nature and therefore talc is produced as secondary mineral.[...]

    2. Flotation of middling particles (i.e. higher than 200 µm) improves with increased pH. This is true in the case when chalcocite is the major copper mineral. In the case of chalcopyrite ore, a lower pH is more desirable (i.e. 8.5–9.5) because at a higher pH, the flotation of chalcopyrite is decreased, especially for the coarser particles.[...]
