Liberation of Gold Using Microwave-Nitric Acid Leaching

The purpose of this study was to liberate gold from sulfide minerals in a gold concentrate through microwave-nitric acid leaching and to separate the light minerals in an insoluble residue using a hydro-separation process. The representative sulfide minerals in the gold concentrate were pyrite with minor galena. Mineralogical characterization was conducted on the gold concentrate using 1715.20

Acid Method for the Digestion of Gold Ore Samples

Solutions to this problem typically propose the use of larger sample sizes, typically 30 g or greater. 3 Furthermore, when using acid digestions, in the absence of hydrofluoric acid, low recoveries have been associated with the encapsulation of gold in the siliceous rock. 1,2,4,5 Here, it is presumed that gold is secreted within a refractory matrix, making it inaccessible to solvent solutions.
