Review of gold extraction from ores - ScienceDirect

01/10/1994· In oxidised ore, the gold can be coated by an iron oxide phase which can significantly slow the rate of cyanidation. Alternatively, gold can be present in an alloy with silver, as electrum, or in a combined chemical form, e.g. in tellurides such as calverite (AuTo) or, less often, as aurostibnite (AuSb2), or occasionally as rnaldonite (Au2Bi). These chemical combinations of gold can also be ...

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

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. The incidence of fine gold's quantity also appears to be related to the gold concentration, as well. If the assay is 2 ounces ...

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or powder.
