The Effect of Sulfur in Rotary Kiln Fuels on Nickel

2020-1-14  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 effect of sulfur in rotary kiln fuels on nickel

2020-10-1  The rotary kiln-electric furnace (RKEF) process is the primary method for extracting nickel from saprolite ores. In this technique, the ore is first calcined and pre-reduced at 850–1000 °C in a rotary kiln followed by smelting in an electric furnace at 1500–1600 °C ( Eliott, 2015, Warner et al., 2006 ).

Calcination Process Development & Calcining

Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type. It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it can move on to transportation or storage.
