The emergence of pneumatic flotation technology has revolutionized mineral processing, offering a more efficient and effective approach to separating valuable minerals from gangue. These cells utilize forced air and slurry mixtures at high velocities to create bubbles, eliminating the need for mechanical agitation.

From 1910 related systems of froth flotation beyond the Elmore's control were introduced in the Americas and elsewhere. As the 20th century progressed, both the scale and scope of flotation treatment increased, so that it became the preponderant mineral-separating method. The pioneering contributions of the brothers are set in context.

Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …

Fig. 4 illustrates a novel homo-aggregation flotation (HAF) process to manage the low flotation rate of value minerals and low separation selectivity in fine particle flotation. Both the value minerals and the gangue minerals are very fine, and the value minerals are to be made hydrophobic and recovered by froth flotation.
