However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns.

Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold onto activated carbon.

Figure 3 – Process categories based on leach recovery vs ore gold grade (McNab, B., 2006) 3. LEACHING IN THE NATURAL ENVIRONMENT Water is a universal low-polarity solvent in action in the nature: Water soluble salts in ores tend to dissolve in percolating rainwater and are transported by gravity.

Mineral Processing Golden Mile ore is of two main types: weathered oxide ore from near the surface which is free-milling with the gold easy to extract, and sulphide ore in deeper ore bodies where the majority of the gold is locked as inclusions in tellurides and pyrites and is difficult to extract.

The key to success for any modern SEM-based mineral liberation analysis system is the close integration of BSE image and EDS X-ray analyses. Integration of the SEM-based quantitative mineral liberation analysis with optical microscope, dual beam systems and X-ray tomography will further enrich the analysis results and the derived user experience.

Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.

Borehole thermal methods have been applied in geothermal exploration, but have seldom been used in mineral exploration. However, this method has potential usefulness in exploration and in geoenvironmental investigations (Ovnatanov and Tamrazyan, 1970; Brown and others, 1980; Zielinski and others, 1983; Houseman and others, 1989).

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold.

Processes based on direct chemical purification and recovery from solution as elemental gold can greatly speed gold processing and virtually eliminate expensive in-process inventories. Refining from scrap. The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction.
