Reduction of low grade iron ore pellet using palm kernel shell

The highest weight loss is obtained at 900 °C in composite pellets with 60:40 weight ratios of iron ore to PKS. This behaviour could be related to the higher carbon content of PKS (more than 50 wt%) which acts as a reductant. Thus, the higher the biomass content, the higher the weight loss of composite pellet.
