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 ...
Bauxite is a mineral that contains varying amounts of combined water and several impurities of which ferric oxide and silica are usually predominant. It is found in a belt around the equator and is generally extracted by open-cast mining. ... then settle to the bottom of the tank where they are removed and transferred to thickening tanks ...
