Ferrosilicon is obtained through smelting and is not directly extracted from natural minerals. Ferrosilicon is an alloy mainly composed of iron and silicon, usually containing other impurity elements such as aluminum, calcium, etc. Its production process involves the smelting reaction of iron ore with high-purity quartz (silica) or silicon metal to produce a ferrosilicon alloy.
In the traditional ferrosilicon smelting process, a high-temperature electric arc furnace or smelting furnace is usually used to heat and melt iron ore, coke (reducing agent) and silicon source (quartz or silicon metal), and perform a reduction reaction to prepare ferrosilicon alloy. The gases produced during this process are vented or used for other purposes, while the ferrosilicon alloy is collected and processed.
It should be pointed out that ferrosilicon can also be produced by other methods, such as molten salt electrolysis or gas phase smelting, but no matter which method is used, ferrosilicon is an alloy product obtained through artificial smelting.
