Froth Flotation Process Detailed Explanation With

Froth flotation is mainly operated undermon techniques : 1. Direct floatation technique In this method, the mineral sticks to the air bubble and the remaining gangue settles down at the bottom. 2. Reverse floatation technique In this method, the gangue sticks to the air bubble and ore particle settle down in the bottom
