Silico manganese is an alloy with 60% to 68% manganese, 14% to 21% silicon , and 5% to 2.5% carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux in a submerged electric arc furnace.the process requires power consumption of about 3,800 to 4,800 kilowatt-hours per tonne

We produce 2 variants of SiMn:

  • High carbon silico manganese
  • Medium carbon silico manganese
