Froth Flotation

This greatly reduces the amount of acid and time that would be consumed to dissolve this feldspar and mica. In froth flotation it is very important to have a fresh, newly cracked surface. It is also just as important for the sample to be of the correct grain size (between 0.25mm-0.5mm), otherwise the grains will either sink or float.

WORLD LEADER IN ADVANCED FLOTATION TECHNOLOGY

TECHNOLOGY Flotation columns derive their name from the geometric shape of the vessel. Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet (7.6m) to more than 50 feet (15.2m). The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.

However, its high performance is limited to a narrow particle size range, e.g., between 50 µm and 600 µm for coal and between 10 µm and 100 µm for minerals. Outside this range, the efficiency of froth flotation decreases significantly, especially for difficult-to-float particles of weak hydrophobicity (e.g ...
