Miargyrite silver ore from the Randsburg district, California

A Novel Technique for Silver Extraction from Silver Sulphide Ore

A novel technique for silver extraction from Ag2S is described. The method utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved. The parameters of the reaction such as pH, the reaction temperature, the complex equilibrium of Ag ion with thiosulphate and the solubility of Ag2S were investigated. Silver ions, obtained by this me...

Mineralogy, Textures, and Relative Age Relationships of Massive Sulfide Ore in the West Shasta District, California

The Devonian massive sulfide orebodies of the West Shasta district in northern California are composed primarily of pyrite, with lesser amounts of other sulfide and gangue minerals. Examination of polished thin sections of more than 100 samples from the Mammoth, Shasta King, Early Bird, Balaklala, Keystone, and Iron Mountain mines suggests that mineralization may be divided into six paragenetic...
