    From the rotary kilns, the ore is moved into the electric reduction furnaces, where approximately 50% of the sulphur in the iron/nickel alloy is removed. The remaining sulphur is removed from the liquid metal in the oxygen converters, and the iron/nickel alloy is then cast into ferronickel granules

    Material residence time in the rotary kiln of a precalciner process is typically 30 minutes. The clinker exits the rotary kiln at ~ 1200 °C and is cooled to ~ 60 °C in the cooler before going to storage and then being ground with gypsum (calcium sulfate) to produce cement. The air which cools the clinker is used as preheated combustion air thus improving the thermal efficiency of the process
