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. Question :?: How much gold can be dissolved by …

Gold refining can be achieved by high-temperature chlorination of the molten metal (Miller process) followed by electrorefining (Wohwill pro cess). The Miller process consists of chlorine injection into the molten bullion by means of an immersed clay tube. This process has three stages: 1.

Invented by Dr. Francis Bowyer Miller, the Miller Process was a game changer in the world of gold refining. It is popular among metal refiners all over the world because – in a nut shell – it's cheap, easy, and produces high-purity gold samples – about 99.95% pure gold. While that level is considered very pure by many standards, some ...

May 8, 2011. #6. Hi HAuCl4. Inquart with zinc, nuke it with nitric, recover the nitric, the silver, the PGMs, the zinc, then pour your fluxed 9995 gold in 2-3 hours and be ready for the next 400 OZ bar melt. At a fraction of the cost. No Miller, no atomizer, only the "big johnson" scrubber, a few buckets, and a furnace.

While gold will go into solution at extremely low pH's, iron oxides will also release iron and put it into solution at very low pH's, as well. This is why the promoters of the modern HCl/Clorox method, with a 4:1 ratio of HCl to Clorox, insist that all forms of iron be removed from your ore prior to leaching.
