Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process knownminution so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm 100 µm, but sometimes sizes smaller than 710 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a

19/12/2006· Selectivity in froth flotation is controlled by the selective adsorption of reagents on minerals at the mineral/water interface. Reagents that impart sufficient hydrophobic character to minerals on adsorption, such that they are rendered floatable, are referred to as collectors.
The flotation concentrates and the tail were filtered, dried and the mass of the mineral, and hence the recovery, was calculated for single mineral experiments. However, the concentrates were analyzed for Cu, Zn and Fe in the tests performed with mixtures of minerals. Calculation of the mass of mineral present in each fraction could then be made.
Flotation cells aremon ore recovery technique applied in ore and mineral mining operations such as copper and gold. the fotation cell is used to foat ore particles away from the crushed ore/rock mix, by driving air into the bottom of the cell to form bubbles which foat to the top of the main body of liquid to create froth.quot
