Dewatering of sinter feed as a bulk draining process

Screen dewatering is widely used in ore dressing operations. A deep understanding of its intrinsic mechanisms can enable the improvement of economic and even mitigation of environmental impacts. The dewatering of iron ore fines has been approached by different ways in recent years. Several authors consider that moisture decrease is essentially linked to residence time, while others attempt to treat this process via parametric modeling. This work explores the comparison between the van Genuchten's porous media dewatering model and the King’s dewatering model, in order to make these two independent models compatible. This approach has the potential to overcome the difficulties of existing approaches by providing a useful and robust modelling alternative.
