How to use an Electrolytic method to separate fine gold

In real terms, I would use physical methods (panning for gold) instead of chemical. If it's a chemistry problem, then you would first have to dissolve the gold. I think cyanide solutions are used to leach gold out of gold ore, but that's nasty s Get price

Extracting Gold from Seawater

Nov 03, 2014Second, gold extraction is indeed a by product, as I am simply trying to find use of my available 5m3/s of seawater flow. I am hoping the the electrolyser energy would be minimal. That is what I am asking here. If gold extraction is not feasible, I may use the water flow to build a lobster farm or a pearl oyster farm. Get price

Electrolysis and Electroplating

Its extraction was not known and pure aluminium was extremely hard to come by. The application of electrolysis turned aluminium from a precious metal to one of the most largely used metals by humans. Aluminium is extracted from its ore by the process of electrolytic decomposition and deposition. Uses of Electrolysis Get price

Refining Gold

The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive dor bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or Get price

Electrowinning and Smelting

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.
