Silicon slag is divided into: industrial silicon slag and ferrosilicon slag

Ferrosilicon slag is the slag cleaned from the ladle during the production of ferrosilicon. Except for containing impurities, its essence is the same as ferrosilicon. It can be re-smelted into ferrosilicon, or it can be directly used in steel plants for steelmaking deoxidation.
