Froth Flotation of Iron Ores

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

A review of effects and applications of ultrasound in

For the UST flotation, the ultrasonic treatment and aeration processes are synchronously conducted. Compared to the UPT method, the effect of the ultrasound on the conventional flotation bubbles is the most apparent feature. The ultrasound will break the conventional flotation bubbles into a smaller size to improve the flotation of fine particles.
