60 Centuries of Copper: The Flotation Process
Flotation depends on the fact that the grains of some minerals, and especially of metals, differ in the degree to which their surfaces can be wetted by a suitable solution. The powdered product of grinding the ore is fed into a series of tanks called flotation cells which are filled with a solution containing various oils capable of forming a ...
Flotation Depressants
This will make the bond between the molecule and the bubble as well as the bond between the particle and the molecule weak. Both will begin to fall free of the bubbles. As these particles that do fall off descend into the cell they become trapped by the tighter smaller bubbles that are caused by the pressure of the slurry in the cell.
Mining
The tanks, known as flotation cells, are agitated; this adds air, forming bubbles to which the hydrophobic minerals link. As a result, the minerals rise to the top of the cell. There, they collect in a launder. The ore that does not float is taken away as tailings, which may be subjected to further flotation.
Flotation test work – from bench scale to modern pilot plant
The pilot plant is a miniature of the real industrial scale flotation circuit, including the different flotation steps and recirculation loads. The pilot plant arrangement is always configured case by case depending on the flotation behavior of the ore and the quality requirements of the concentrate.

Comprehensive Guide to Flotation Machines: Principles
Mechanical flotation machines are further divided into three subcategories: Self-aerating cells: These cells rely on the suction created by the impeller to draw in air and disperse it into the slurry. Forced-air cells: Pressurized air is directly supplied to the cell, providing a more uniform bubble distribution.
