Flotation


This separates valuable minerals from unwanted gangue materials in  the ore. It is performed in various circuits such as:


•     Standard flotation
•     Reverse flotation
•     Bulk flotation and 
•     Differential flotation


Bulk flotation is practiced at Mimosa which will capture all the metals  in one concentrate.
In reverse flotation the gangue is floated leaving the valuables behind. 
Bulk flotation is employed when there is more than one valuable  mineral. In differential flotation, the bulk flotation concentrates is  separated into various products.
