FERRONICKEL PRODUCTION AND OPERATION

 · 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]. For this route lateritic ore is screened, crushed and blended to produce a consistent process plant feed with defined ratios of iron and nickel as well as Si02 and MgO.


Modelling of Nickel Laterite Smelting to Ferronickel

 · The recoveries of nickel, cobalt and iron are shown in Figure 3(a) for the feed having an Fe/Ni ratio of 10. The recovery of nickel is close to at 20 kg/tonne of carbon, with the cobalt recovery being about 90%. Iron recovery increases almost linearly with the quantity of carbon in calcine.
