Froth Flotation Hazen Research

Froth flotation for separating discrete mineral particles from gangue was developed in the early 1900s and depends upon differences in the surface chemistry of the mineral species involved. We have studied not only the flotation of sulfides, gold ores, iron ores, coal, oil shale, and many other nonmetallics, but also soluble salts, oxides, and some uncommon materials from waste streams.

Model Predictive Control for Froth Flotation Plants

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral. The resulting froth layer is then skimmed to produce the ...
