Gold metallurgy - AccessScience from McGraw-Hill

Extracting gold from ores, refining it, and preparing it for use. Total world resources of gold are estimated at about 83,000 tons (75,000 metric tons). South Africa has about half of these resources, and Brazil, Russia, and the United States have about 12% each. The United States produces about 330 tons (300 metric tons) per year.

Gold Metallurgy and Leaching Process

2015-6-24  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:

Metallurgical Test Work: Gold Processing Options,

2016-1-1  The recovery of gold from heaps or dumps is often seen as a specialty area of gold metallurgy or, at the least, gold processing (Van Zyl et al., 1988). A requirement to be able to scale up from laboratory tests to field application has seen the need to develop specific procedures and techniques, in order to facilitate this and minimize risk.
