rotary kiln electric furnace nickel italy pdf

rotary kiln and then smelted in an electric furnace. The product of the RKEF process is crude ferronickel (iron-nickel alloy), which needs to be refined for impurities such as sulfur. Sulfur is one of the most harmful impurity elements in ferronickel and degrades mechanical properties of the material.

Modelling of Nickel Laterite Smelting to Ferronickel

to as the “RKEF process” (Walker et al., 2009) due to its use of rotary kilns (RK) and electric furnaces (EF). Typical industrial data was given by Warner et al. (2006) and part of this is shown below for several smelters. Table 1 – Typical industrial data from Warner et al. (2006) Laterite feed Alloy Ni grade Slag/alloy mass ratio


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].


The plant is based on the rotary kiln – electric furnace (RKEF) process, with two rotary kilns and a single a large furnace to achieve economies of scale in capital and operating costs.
