control of slag formation in the electric furnace smelting

Two-thirds of the globalnickeloutput can be attributed to therotary kiln-electric furnaceprocess. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (∼1600 °C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the
