60 Centuries of Copper The Flotation Process

In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

Bulk flotation vs. Selective flotation Froth Flotation

In Selective Flotation by the action of reactive you can have in the concentrate one ore that you want. The quality of concentrate its better than Bulk Flotation. When you start a process, you start whit Rougher Cells (could be Bulk Flotation) then you go for a Cleaner Cell (could be in this case Selective Flotation).

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
