Most mines do not have the refining capacity to separate the silver from the gold and the bars are sent to a commercial refinery for producing the 99.99% gold and silver ingots that are sold on the commercial gold market. Once the carbon has been stripped, it can be reused after recharging it in a kiln, by heating it to around 1300 degrees F ...
The technology boom for developing pure gold continued with E.B. Miller's process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill's electro-refining process (introduced in Hamburg, Germany, in 1878). In fact, gold with purity of 99.99 percent is created using a combination of the processes.

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell. The refiners will then pass an electric current through the cell. At the end of this process, the gold will be 99.99 percent pure. Reclaiming the Mine; No gold .

The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric ...
This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes.
