3. Limonite Flotation process

Limonite has a complex structure consisting of hydrated iron oxides. The flotation method is unique in its ability to selectively separate the desired minerals from the unwanted gangue material using surfactants, thereby improving the overall efficiency of ore processing. Flotation involves the addition of reagents to render certain minerals hydrophobic while making others hydrophilic. The froth brings the hydrophobic minerals to the surface while leaving the hydrophilic materials in the pulp phase. Flotation selectively concentrates the valuable components such as iron oxide while minimizing impurities.

The limonite flotation process separates the limonite mineral from other impurities through a series of flotation stages. The success of the process depends on a variety of factors, including pH control, reagent selection, and particle size distribution.
