Concentrate Dewatering & Thickening

The size of a concentrate thickener is determined by the tonnage of solid material to be dewatered, the amount of water in the pulp, and the settling rate of the solids. In the absence of specific data, it is usual, for the purposes of rough calculations, to allow 10-15 sq. ft. of tank area per ton of dry concentrate produced per 24 hours.
