Abstract the flotation of desired mineral ores is selectively depressed by the use of an effective amount of a polyoarboxylic acid or salt thereof in a reverse flotation process. as an example, the flotation of ironcontaining minerals, such as iron oxides or iron powder, is selectively depressed when compared to the flotation of silicate gangue thus facilitating the recovery of the desired ...

3. kaolin flotation. the flotation method mainly uses the difference in physical and chemical properties of the surface between gangue minerals and kaolin to treat kaolin raw ore with more impurities and lower whiteness, and removes its iron, titanium and carbon impurities to achieve low grade kaolin comprehensive utilization of resources.

In the flotation process, air is bubbled through a suspension of fine iron ore in water to which a small quantity of flotation reagent is added. this reagent modifies the surface of either the iron oxide or the principal gangue component, normally silica, so that these particles attach themselves to the air bubbles and are carried to the surface,
