Electrowinning and Smelting

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. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).

The environmental impact of gold production

the gold from ore, carbon adsorption to extract the gold from the cyanide solution and electrolytic refining and chlorination to refine the gold. The LCA assessed production from both nonrefractory ores, which are relatively easy to treat, and refractory ores where the gold is 'lockedin' and requires more complex processing.

Everything You Need to Know About the Process of Smelting Gold

Smelting gold is also useful if you have jewelry or gold pieces that you never use. Selling pure gold resulting from smelting those old pieces will return more value and allow you to receive more cash with just a little time and effort. Gold smelting is also an alternative to gold melting since many people struggle to melt gold successfully.

3 Ways to Assay Gold

· 2. Mix acids to form aqua regia. Aqua regia is Latin for "royal water." This solution is used to remove gold from a scrap of metal or an ore. To make it, mix three parts hydrochloric acid and one part nitric acid. For example, 400 mL of aqua regia will contain 300 mL of hydrochloric acid and 100 mL of nitric acid.
