The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.

Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
Editor's Note: In our last article, Calla Gold, a Santa Barbara jeweler specializing in custom jewelry design and jewelry repair, described gold plating and its best practices.

Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold …
Jun 02, 2016· If the concentration of silver is roughly equal to or greater than gold in the PLS, the silver can actually be used as a collector to facilitate the electrodeposition of gold. The resulting deposit is a gold-silver alloy. Electrowinning is also used in the refining industry to produce high purity silver from low grade residues and scrap materials.

The aim is to get all end users/retailers of gold to adhere to set of principles that encourage sustainable mining. Campaigns such as 'No Dirty Gold' are driving the message that the mining industry is harmful (for the reasons noted above), and so must be cleaned up. Also, NGOs are urging the industry and consumers to buy sustainably produced gold.
How Raw Gold is Refined into Pure Bullion. ... In fact, there is likely 8 times more gold in Earth's watery depths than the total amount of gold mined on land up to the present. However, the logistics of setting up a mining operation in the ocean make gold extraction there infeasible. ... Gold Bullion Buying Guide;

mineral processing plant that uses only water to recover very fine grained gold and other heavy mineral grains. Three well-known, former Homestake metallurgists helped design this mill in 1994. It was built for portability, quick set-up, start-up, and re-configuration, and reliability in remote areas.

One bed volume (thirty minutes) into the elution stage the eluate pump is started and pregnant solution from the eluate tank, is pumped up into the electrowinning cell on the first floor of the goldroom. It then flows back into the eluate tank. As the solution flows through the electrowinning cell, gold is plated on to the steel wool cathodes.
