Development of the Process of Manufacturing Pig Iron for Cast Iron from Copper Slag

摘要

A study on the manufacturing pig iron for cast iron from copper slag has been conducted to recover iron-copper matte to be used as a raw material for foundry industries. The copper slag was reduced by carbothermic reaction at 1300°C for 2 hours using electric furnace. Finally, iron-copper matte was successfully obtained with about 93 wt.% and 5 wt.%, respectively.
