Recent Developments in Dewatering Ultra-Fine Coal

Recent Developments in Dewatering Ultra-Fine Coal

With the demand for coal soaring over the past 12 months, the need for optimising coal processing is at an all-time high as companies seek ways to maintain and increase the highest levels of throughput.

In a recent presentation David Williams, Professor & UQ Researcher with the University of Queensland shared some recent developments in the process of dewatering ultra-fine coal. The extraction of ultra-fine coal is increasing, its fine pore sizes present dewatering difficulties, and as the proportion of ultra-fine coal increases, the moisture content of the composite product necessarily increases. In-plant dewatering essentially involves the application of pressure over the time that the product is exposed to dewatering.
