Ferrosilicon Production | 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.

Ferroalloy Refining Process
Process flow: the liquid silico-manganese alloy produced in the submerged arc furnace and the high-manganese slag produced in the refining electric furnace are poured into the shaking ladle. The shaking allows the slag and metal to be highly emulsified, accelerates reaction rate of desiliconization, and discards the final slag (low-manganese slag).

A review on characteristics of silico-manganese slag and its
Silico-manganese slag is a byproduct of silico-manganese alloy production, and its major oxide components are SiO 2, CaO, Al 2 O 3, and MnO. It's chemical composition similar to blast furnace slag, except it is more acidic due to higher SiO 2 and lower Cao and also contains ∼10 wt.% MnO. Depending on the process of cooling, the molten slag is ...
