Flotation Results. Figure 2 shows the effect of grinding fineness on recovery rate of copper. It is observed that a rise of the proportion of the grinding fineness of −0.074 mm from 60 to 80% obviously increased the copper recovery, then decreased when it exceeded 80%. This is because the initial appearance was dissociation fragmentation ...

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].

JEE 2022: Basic Principle of Froth Flotation Process
Basic Principle of Froth Flotation Process. There is a first step in breaking down ore into small pieces. This makes it easier to separate it from the water because it has more surface area. The ores are first ground into small pieces and mixed with water. When you make something, it's called a slurry.
