Sulfide Mineral Flotation Maurice C. Fuerstenau, Subhash Chander, and Ronald Woods INTRODUCTION Froth flotation was developed at the Broken Hill mine, Australia, a century ago with the flo- tation of the common sulfide mineral, sphalerite. With this development, billions of tons of worthless rock containing a variety of valuable metals became ore.

Froth flotation takes advantage of a minerals surface properties as a means of separating valuable minerals from non-valuable gangue. When air is introduced into the mineral slurry, the hydrophobic particles (most often valuables) attach to the air bubbles and rise into the froth phase where they are eventually collected.

To obtain concentrates with highest possible purity and recovery rate, the flotation process usually consists of several stages which are controlled by expert systems. Various sensors for particle size, pH, density, and other properties are installed.

The surface conversion of sulfide mixtures from a sulfide/sulfide to an oxide/sulfide system facilitated separation using the oxide collector Flotinor FS-2. Therefore, the approach of applying selective surface oxidation of mineral mixtures by low-temperature plasma pretreatment seemed to be a promising strategy for improving the separation efficiency of different sulfides by froth flotation.
