FERRONICKEL PRODUCTION AND OPERATION
Production of ferro-nickel by pyrometallurgical process is still the most widely utilized method for the processing of nickel lateritic ores. The Ni-content of lateritic ore is normally low and in the range of 0.8 3 - %. The most important production route is the RKEF (rotary kiln -electric furnace) process [ 1, 2, 3].
