//
Diemme Filtration has conducted intensive test programs for several nickel laterite HPAL operations with very positive results. Pressure filtration was found to give the best results (productivity, cake dryness and stability, etc.) in comparison to other dewatering technologies. This paper presents summarised details of these testing programs and the advantages of pressure filtration for dry stacked nickel laterite tailings.
