Currently, the main carbonaceous material for Mn-alloys production is solid carbon, i.e. coke, charcoal and petroleum coke, which is produced under massive CO2 emissions. Due to the easy purification, high carbon activity and low CO2 emissions, natural gas stands in the advantage status compared with conventional reducing agents. The aim of present project is to develop a new technology for production of Mn-alloys using natural gas as a source of carbon. Experiment results indicated that injection of CH4 gas into melted slag improved slightly the reduction of MnO and SiO2. However, the metal yield was far from the theoretical value duo to a relative low residence time of CH4 in the slag. Alternative approach was to use of carbon black as reductant, which was produced by CH4 decomposition. The preliminary experiment results showed a high reduction rate by using carbon black.
