froth flotation of sulfide minerals
(PDF) Sulfide Mineral Flotation Morgan Zhao -
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 : RECENT TRENDS Flotation of
2011-12-1 History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for
