Flotation Froth
The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].

What Is The Difference Between Froth Flotation And Gravity …
The major advantage of froth flotation is that it is better at recovering fine particles than gravity separation, as the froth allows fine particles to float to the surface, while gravity separation is limited to heavier particles. Additionally, froth flotation requires less energy than gravity separation, making it a more cost-effective option.
