To make gold chloride, we need to dissolve gold in aqua regia. (mixture of nitric acid and hydrochloric acid at molar ratio 1/3) In my case, I have 18K gold scrap, but the purity of gold makes no difference as gold will be purified to 24K during the process.
Aug 07, 2017· But let''s say the break even point would be on oz of gold per device. The concentration of gold in seawater is about 13 ug/m^3 (not mg), so to extract one troy oz of gold you would have to process about million M^3 of seawater. If the device could average 10 liters/second it would do that in about 7 years. That''s a tall order.
Sep 13, 2013· Okay, now for the hard part. In the last post, we added vinegar, in small increments, to a mixture of sodium (or calcium) hypochlorite bleach and salt .
When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators. ... dissolving the gold.
One of the safest and most advanced aqua regia gold refining systems available. The Shor AR3G Aqua Regia Gold Platinum Refining System is ideally suited for refining of electronic scrap as well as jeweler''s polishing and bench sweeps. This system will also refine jewelry, nuggets, dust and all other forms of gold.
Gold is a stable metal and does not react with oxygen corroding. Because it is stable, it will not change colors when exposed to vinegar. If the gold piece changes colors, it is not real gold. Gold plate will turn black when exposed to vinegar. Run the gold piece under cool water or spray it with a water bottle to remove the vinegar.
If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 500 mV using NSO3 and your gold .

Feb 01, 2016· The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore.
Gold is also dissolved by liquids containing chlorine and bromine, but the action is much slower than that of aqua regia; and subject to the same difficulties if silver is present; heat assists the dissolution. Iodine only dissolves gold if it is nascent, or if heated with gold and water in a sealed tube to 50°.
