silicothermic process of manganese

Transformations in the Mn-O-Si system using concentrated ,

May 15, 2019· Solar energy has a great potential in high temperature process as the production of ferroalloys • We proposed the silicothermic reduction of the oxide of manganese (IV) using concentrated solar energy • Silicon-manganese mixtures and silicomanganese were obtained by silicothermic reduction of the oxide of manganese (IV)

Manganese ore pre-reduction using a rotary kiln to ,

Lindstad, 2007) In a silicothermic process, first, low-carbon silicomanganese is produced as the intermediate product Next, this silicomanganese is charged into an electric furnace along with manganese ore to be refined Then, the manganese oxide in the manganese ore is reduced by the silicon in silicomanganese, thus obtaining MC/LCFeMn

Kinetics of Silicothermic Reduction of Manganese Oxide for ,

Mar 28, 2017· Abstract The kinetics of silicothermic reduction of manganese oxide from MnO–SiO 2 –CaO–Al 2 O 3 slags reacting with Fe-Si droplets were studied in the temperature range of 1823 K to 1923 K (1550 °C to 1650 °C) The effects of initial droplet mass, initial droplet silicon content, and initial slag manganese oxide content were studied
