Limonite, which accounts for nearly double the amount of saprolite available globally, is more amenable to processing via hydometallurgical techniques, ... The RKEF, or Rotary Kiln Electric Furnace method, is a pyrometallurgical approach to producing ferronickel. As a pyrometallurgical technique, this method is best suited for ores that are ...
RKEF can produce a ferronickel product with over 10% nickel content for use in 300-series stainless steel. There are a number of limitations—RKEF generally requires high-grade saprolite feed (>1.8% Ni, <20% Fe). It is not well suited to process lower-grade limonite feed economically. Electricity availability is a key limitation of RKEF.
