How to Use Bleach on Gold Ore to Remove Gold Sciencing
When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore. This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a two-to-one ratio of

Leaching of an oxide gold ore with chloride/hypochlorite
01/06/2007· An oxide gold ore was subjected to chloride/hypochlorite leaching at room temperature. The effects of three factors, including Ca(OCl) 2 vs. NaOCl, OCl − concentration, and HCl concentration on gold leaching performance were investigated. Due to formation of CaOCl + complex in solution and hence less reactivity, calcium hypochlorite produces a sluggish gold leaching kinetics, taking twice

In order to verify that the gold is present in the solution, you can do a Stannous test. The gold is then "dropped" from the solution by using small additions of Sodium MetaBiSulfate. That gold sludge is then washed and dried, and then melted in a crucible

How to Leach Gold Ore With Chlorination Sciencing
Pour in the hot water, bleach and HCL. The mixture should be 15 percent sodium hypochlorite and 33 percent hydrochloric acid. The mixture should cover the rocks, so multiply the mixture until the rock is covered. Insert the ORP meter so the probe side is in the water mixture. An ORP meter is used to measure oxidation, which is required to break the gold out of the rock. In fact, according to
