Off -Grade Silicon Metal

• 

Thesiliconoff-grade is a by-product from production ofsilicon metalof ≥99% purity. To ensure the quality of the silicon metal, top portion of the melt is separated when draining from the electric-arc furnace. The less pure portion of silicon metal typically contains higher contents of iron, aluminum, calcium and other slag. With the employment of density separation machines, different grades of off-grade silicon are segregated efficiently.
