pine oil (yes activators 2021; Accepted 16 May 2021 Abstract The paper is about the froth flotation process and its application.Froth flotation was invented in the early 1900s in Australia by C.V. Potter and around the same time by G.D. Deprat. The process was adapted and applied to a wide variety of materials to be separated. In the 1960s the flotation technique was adapted for deinking recycled paper.Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH,
