What are the production costs of ferrosilicon 75?
The main raw materials for the production of ferrosilicon 75 are silica, semi-coke and iron oxide scale.
Silica is the main source of silicon in ferrosilicon 75. Semi-coke is used to reduce the silicon content of silica. Iron oxide dross is used to adjust the composition of ferrosilicon, especially the iron content. It also reduces the silica content of silica.
