production of metallurgical silicon from quartz

The silicon thus obtained has a purity of 97% to 98%, and such silicon can be generally used for metallurgical purposes. If higher grade silicon is to be obtained, it needs to be refined to remove impurities to obtain metal silicon having a purity of 99.7% to 99.8%.
