Chlorine gas is highly reactive because the bond between the two chlorine atoms is weak. It is a colorless and highly pungent solution of hydrogen chloride in water. First, the gold is dissolved into a solution of bleach and muratic acid to create Auric Chloride (Au₂Cl₆). Recycle Gold old CPU processors computer recycling ic chip gold wire bonds. In this study, the authors investigated the capability of a hot mixture of hydrochloric acid and ground manganese (IV) oxide to dissolve gold metal either under atmospheric or pressurized conditions. A high level of 9 g/L of added HCl causes HClO to be very reactive, producing very fast kinetics, reaching 67% gold extraction in 4 h. It also causes a faster consumption of hypochlorous acid, through catalytic decomposition (by NiO and CuO) and disproportionation. An oxide gold ore was subjected to chloride/hypochlorite leaching at room temperature. %���� Muriatic Acid + Clorox Bleach is dissolving my gold, but Sodium Metabisulfate (stump out) is not dropping the gold back out in pure form it's only changing colors of my solution. but HCl is also used to remove/dissolve the base metals associated with plated gold.

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 the time (46 h) to achieve maximum gold recovery of 58% compared to sodium hypochlorite. but nothing happens with sodium metabisulfite . %PDF-1.5 Hypochlorous acid reactions with sulfide and ferrous content of ore proceed very slowly in the pH range of 4–11. Then, the sodium bisulfate is introduced into the auric chloride to break the bonds in between the gold and the chlorine causing pure gold powder to precipitate to the bottom of the beaker.
