The SiO 2 content silica used for ferrosilicon production should be more than 97% because the reducing process of SiO2 requires a very high temperature. If with low content of SiO2, the content of Al2O3, and CaO in the silica will relatively high. This requires a higher reaction temperature, which in turn increases the consumption of power and reduces agents.
