Flowsheet options for processing copper gold and gold …
Copper and gold have similar cyanide metallurgy depending on the nature of the minerals present. 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 …
FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES
This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: • Simplicity • Favorable capital • Favorable operating costs, which
