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.
