Hypochlorite Leaching of Gold Ore. Leaching pure gold with an acidic sodium hypochlorite solution has been demonstrated to be effective. The initial rate of gold dissolution was extremely rapid. In a leaching solution containing 1 g/L NaCl, 1 % HCl and 2 % NaOCl, nearly 90 % of the gold was extracted in only 30 minutes. Inquire Now

The concept of hypochlorite treatment prior to cyanidation in the heap leaching of low grade carbonaceous gold ores is discussed. Laboratory column leach tests using a low grade carbonaceous ore were performed to investigate the effects of pH, hypochlorite consumption and concentration, and bed height on total gold extraction. At high pH, hypochlorite stability increases and thus, hypochlorite ...

2017-4-24 Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold

2021-5-23 As far as the gold on pottery goes you would have to process a heck of a lot since it's only a few millionths of an inch thick. You can kill the cyanide with calcium hypochlorite for disposal. I once got about 3 oz of gold off mil spec connector pins but I had to process about 27 pounds of them. Good luck and be very careful with the cyanide.
