Mineral processing - Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

How do you calculate the difference between wet ton vs dry ...

Apr 28, 2016· Hi, The difference is calculated by knowing the dry solid content of the sludge. For sludge produced in wastewater treatment plants, we talk about moisture content in terms of percentages or g/L. This is the amount of dry solids per 1L of sludge. When you have 1 ton of sludge at 20% dryness, this equates to 0.2 t of dry matter (1 x 20%).
