2020-11-15  Coal is used as a common fuel for calcination of nickel laterites in rotary kiln. Due to the depletion of high-quality coal with low impurity content, high-sulfur coal has been used as fuel in nickel laterite rotary kilns. This investigation examines the behavior of sulfur present in the rotary kiln fuel in the calcination stage.

The calcination-partial reduction experiments were conducted in a furnace at 900 °C for a 2-hour residence time. Various reducing gas mixtures representing combustion product of rotary kiln fuels (i.e., coal) were contacted with the ore. The sulfur content of the resulting calcines were measured by ICP-AES analysis. At constant PCO, the sulfur content of the calcine increases linearly with an ...
