The thickening process can be monitored and improved by measuring density in the feed of the system, in the feedwell and in the underflow. Combined with a flow meter, the mass flow can be calculated, giving real-time insights about the effeciency of the thickener operation.
In mineral processing operations, water is very important and therefore water recovery plants have an important position. According to CRC Care 2013, every year more than 10 billion tonnes of tailings are produced by mining activity. Thickeners can be used as a water recovery system, to meet requirements in the recovery and reprocess of water. A growth of 1 or 2% in underflow density can return large amounts of water to the operating installations. The increasing of density is also important to avoid accidents in tailings dams, which can collapse when there is too much liquid pumping to the dams.
