The Effect Of Sulfur In Rotary Kiln Fuels On Nickel

Rotary Kiln - Electric Furnace (RKEF) process is a pyrometallurgical technique to extract nickel from laterite ores. It is essentially a two-step process where the ore is first calcined in a rotary kiln and then smelted in an electric furnace. The product of the RKEF process is crude

Ferronickel smelting is the most widely practiced technology (Stober et aI., 2008). In this process (the Rotary Kiln - Electric Furnace or RKEF process) the ore is blended with coal or coke and then dried and calcined in a rotary kiln at 900-1 ,000oC. Some pre-reduction of the iron and nickel may occur during this stage (Figure 3). 5
