Nickel Ore Rotary Kiln Calcination
Metallurgy chemical kiln is mainly used in iron ore magnetic calcination, silicon thermal refining magnesium, chromium nickel ore calcination, refractory calcination and active lime and calcined dolomite for steel mill and ferroalloy works.Rotary kiln introduction A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process
The effect of sulfur in rotary kiln fuels on nickel
01/10/2020 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).

The Effect of Sulfur in Rotary Kiln Fuels on Nickel
This study investigates the role of sulfur content of rotary kiln fuels on the composition of the calcine. The calcination-partial reduction experiments were conducted in a furnace at 900 oC 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

Modelling and optimization of a rotary kiln direct
The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company
