rotary kiln electric furnace process

The Araguaia Nickel Project will utilise a low risk proven process technology called the Rotary Kiln Electric furnace(RKEF)to produce a high-grade ferronickel product to sell into for the stainless-steel market. Today theRKEFprocess is in operation in over 40 mines around the world and accounts for a significant portion of the nickel produced annually
