The Theory and Application of Alkaline Sulfide Leaching and Nitrogen Species Catalyzed Pressure Oxidation Hydrometallurgical Technologies: Corby Anderson1; 1Colorado School of Mines
    This presentation will cover the development, fundamentals and applications of two distinct industrial hydrometallurgical technologies. First is Alkaline Sulfide Leaching (ASL) which was commercialized for production of antimony. In its 60 year history, the ASL plant provided antimony metal and compounds while also abating copper smelting penalties. Aspects of the thermodynamic and kinetic fundamentals and some economic aspects of this selective technology will be elucidated along with applications to gold, arsenic, mercury and tin from primary and secondary sources. The second technology is Nitrogen Species Catalyzed Pressure Oxidation (NSC). The NSC plant was commercialized as a low temperature process for treatment of copper concentrates with non cyanide precious metals recovery. The facility operated successfully for over a decade. Again, some of the thermodynamic and kinetic fundamentals and some economic aspects of this selective technology will be elucidated along with applications for molybdenum, nickel, cobalt, zinc, PGM and gold bearing materials.
