Definitions

  • the apparatus comprises a submerged electric arc furnace 5 for smelting feed mixture 1 comprising at least manganese ore sinter 2, reducing agent 3, and fluxing agent 4.
  • a layer containing liquid manganese alloy and a layer containing slag above the layer containing liquid manganese alloy are formed in the smelting in the submerged electric arc furnace 5.
  • the burner 7 is preferably connected to the pre-treatment silo 8 and the pre-treatment silo 8 is preferably connected to the submerged electric arc furnace 5 so that gases such as oxygen from the ambient air is prevented from entering the burner 7, the pre-treatment silo 9 and the submerged electric arc furnace 5 so as to prevent uncontrolled reactions of said feed material 1.
