Industrial NSC Hydrometallurgical Precious Metals Recycle

Abstract

In the processing of many concentrates and ores such as copper, zinc, nickel and cobalt hydrometallurgical methodologies are becoming more prominent. Among these, one industrially proven pressure leaching process is Nitrogen Species Catalyzed Pressure Leaching (i.e. NSC). This technology is applicable to many concentrates and ores. As well, it has been used on an industrial scale for the recycle of base and precious metals. This paper outlines the fundamentals and actual industrial application of this technology to the industrial recovery and recycle of precious metals.
