Dewatering and water recycling are therefore essential for mineral processing operations. Copper is one of the most widely used metals in various industries. About 20 million tons of copper were produced worldwide in 2019 (Esmaeili & Aslani, 2019). Large amounts of tailings are produced when copper minerals are concentrated by flotation.
Frothers are usually added to the pulp just before its entrance into the flotation machine. The quantity of frother varies with the nature of the ore and the purity of the water. In general from .05 to .20 lbs. per ton of ore are required. Some frothers are more effective if added in small amounts at various points in the flotation machine circuit.
