A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being …

noted that copper sulfide (Cu 2 S) minerals have good flotation response to anionic collectors such as amyl, iso-propyl and butyl xanthates, and the concentrations of collectors added usually vary between 3 and 300 g per tonne. Rougher concentrates and middlings are usually reground and floated for maximum recovery.

This is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers. In a simplified sense, the role of the flotation machine is twofold: to maintain an agitated (mixed) pulp in the cell, and; to introduce air bubbles into the agitated pulp.
