The smelting process is about extracting the precious metal from its ore. The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.

Currently liquid–liquid extraction is employed commercially by Matthey Rustenburg Refiners for the separation of copper, cobalt and gold. The separation relies on the desired metal being selectively extracted from …
Using Electricity as a Method of Gold Extraction. One hundred grams of 100 mesh ore were placed in a jar with 500 grams of water and 15 grams of sodium chloride. This was electrolyzed with a …
Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast gold-bearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves, in ...

But the cold strip works up to a certain limit that should have been detected with proper mineralogical characterization. If the amount of copper is such that the ore really corresponds to "low grade copper with traces of gold", then a copper removal step employing for instance the SART process might be mandatory, in addition to the cold strip.
