Ferrosilicon is manufactured from a material containing silica and a raw material containing iron by injecting these materials, possibly together with a reducing agent, with the help of a carrier gas into a plasma gas. The silica and the iron raw material, possibly with the reducing agent, heated in this way are then introduced with the energy-rich plasma gas into a reaction chamber surrounded by a solid reducing agent in lump form, the silica thus being brought to the molten state, being reduced and reacting with the iron to form ferrosilicon. |
