This paper discusses the use of froth flotation as a means of removing metal containing species from a variety of feed streams that generally fall into the classification of waste streams. The variability in solid composition, degree of oxidation, water chemistry, and levels of organic/inorganic contaminants associated with waste streams implies that the collector chemicals used in any flotation process must be much more selective than typically required in normal mineral ore flotation systems. Several examples of such work currently underway will be illustrated showing the potential of flotation to upgrade metal-containing waste streams.
