An Overview of Optimizing Strategies for Flotation Banks

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 exploited.

How Froth Flotation Works - Mineral Processing & Metallurgy

To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids. This is very important because the slurry will be treated chemically and air will ...
