    Nickel Nickel Laterite Processing: Can New Technologies ..

    Nickel laterites accounted for 60–65% of nickel production in 2017. The Big Three Nickel laterite processing is dominated by three main processes: rotary kiln-electric furnace (RKEF), blast furnace production of nickel pig iron (NPI), both pyrometallurgical processes, and the hydrometallurgical high-pressure a

    In the recent years, ferronickel has been used as a substitute for electrolytic nickel for alleviating the cost of stainless steel production. Rotary kiln‐electric furnace (RKEF) smelting is currently the world‐wide mainstreaming process for ferronickel production from nickeliferous laterite ore, in spite of the high power consumption.

    Further, it is preferred that the high grade nickel product is combined with a feed material for a Rotary Kiln and Electric Furnace (RKEF) and processing that combined product in an RKEF process, preferably to produce ferronickel. It is most preferred in this process to remove ferric iron as an impurity by precipitation.

    An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in the rotary kiln-electric furnace (RKEF) for the smelting of ferronickel alloy. One of the measures is to recover the waste heat of exhaust gas from the rotary kiln for preheating and dehydrating the wet laterite ores in the rotary dryer.
