Through various pre-treatment options, the goal is to achieve sufficient gold recovery in the most economical way possible. This article serves its purpose in providing an overall guide to gold processing, and the associated processing options for each gold ore classification. References. Brooy, S. R. 1994. Review of gold extraction from ores.
The processing of gold copper and copper gold ores can be highly problematic, site specific and the process selection is dependent on ore grade, mineralogy, acid leach behaviour, cyanide chemistry, product saleability and environmental considerations. The production of a copper gold concentrate is also an option where the copper is of a marketable grade.
