Oct 01, 2020 · The rotary kiln-electric furnace (RKEF) process is the primary method for extracting nickel from saprolite ores. In this technique, the ore is first calcined and pre-reduced at 850–1000 °C in a rotary kiln followed by smelting in an electric furnace at 1500–1600 °C (Eliott, 2015, Warner et al., 2006)
