In mineral processing plants, thickening is intended to remove the water content of pulp so that the mineral processing products meet the requirements of the other processes. Usually the solid mass fractions of concentrate and tailings are 30–40% and 8–20%, respectively. After thickening, the solid mass fraction of concentrate can be 65 ...
