use of high carbon silico manganese slag
Silico Manganese Silico Manganese is an alloy with 65% to 68% manganese, 16% to 21% silicon, and 15% to 2% carbon It is produced by smelting of slag from highcarbon Ferro Manganese or of Manganese ore with coke and a quartz flux Smelting temperatures are high and greater energy is needed to reduce the quartz to silicon .
