Pioneer Gold Pioneer Gold Coins Mormon Territory

Pioneer gold coins exist because when gold was first discovered in the South in the early 1800’s and later in the West in 1849, government facilities did not exit to convert oar or dust into bullion or coin. In the South private mints like the Bechtler’s and Templeton Reid filled this vacuum by opening assay offices.

Gold Metallurgy and Leaching Process

Jun 24, 2015 Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:
