Hcl/Bleach process Gold Refining Metal Extraction Forum

2011-7-23  Normaly 15% sodium hyphochlorite and 33% hydrochloric acid are used as bleach and pool acid, therefore a dosage of approximately more than 391ml of sodium hypochlorite and 90.9 ml of acid will produce at least 68g of chlorine which in turn is consumed by the reaction with gold.

2011-2-22  Feb 22, 2011. #2. If you mix more than a few milliliters of equal portions of 32% HCl (muriatic acid) and 5% sodium hypochlorite (bleach), you are going to make one hell of a large cloud of chlorine gas. Boiling the mixture will only expand the cloud. Chlorine is the active ingredient in dissolving the gold in the HCl-Cl reaction.

Leaching of an oxide gold ore with chloride/hypochlorite ...

2007-6-1  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 ...

You mix the H2O2 (e.g. 20%) one part with two parts of your 32% HCl and put the metal scrap in the mix. All metal stuff will dissolve, the gold also. After the reaction, you boil for a while to destroy remaining H2O2 and then you ...

The Chemistry of the Extraction of Gold - SAIMM

2011-5-29  For example, gold does not dissolve in either nitric acid (an oxidizing agent) or hydrochloric acid (a complexing ligand), but dissolves quite easily in a mixture of the two, aqua regia. Whether they are solid, in solution, or in the gaseous state, gold compounds are invariably bound covalently, and by far the majority are complexes. *
