Oct 21, 2016 The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp as a rule the underflow contains 55 to 65 of solids, while 70 to 80 of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
De-watering is an important process in mineral processing. The purpose of dewatering is to remove water contained in particles. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to
