A New Ferro Silicon Manufacturing Process
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.

How silicon is made
For maximum purity, a chemical process is used that reduces silicon tetrachloride or trichlorosilane to silicon. Single crystals are grown by slowly drawing seed crystals from molten silicon. Silicon of lower purity is used in metallurgy as a reducing agent and as an alloying element in steel, brass, alumiinum, and bronze. ...

Our Silicon Production Process
The basic process for producing silicon has remained unchanged for decades: quartz or gravel (SiO2) is blended with a carbon source and superheated in a submerged arc furnace. As the mix heats, the carbon reacts with the oxygen in the quartz and forms CO gas, thereby reducing the quartz to 99% silicon in molten form. ...
