2018-3-10 1. Introduction. Water is ubiquitously used in mineral processing plants. While in the plant it is required for valuable mineral extraction, often via flotation, it is also used as a vehicle for both the transport of the commercial product (ore concentrate) and the residue (tailing). In either case water acts as a vehicle both for separation and transport, and is subject to losses in
