How to Use Bleach on Gold Ore to Remove Gold Sciencing

24/04/2017· How to Leach Gold Ore With Chlorination. Updated April 24, 2017. By Maria Kielmas. 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

Leaching of an oxide gold ore with chloride/hypochlorite

The process of gold extraction from ores via its absorption in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery. It was first introduced by Karl Friedrich Plattneraround 1848, and at that time promised to revolutionize the processes for gold extraction. By degrees it was found that only a very clever chemist could work this process with practically perfect results, for many reasons. Lime and magnesia might be contained in the quartz, and would be attacked by the chlorine. These consum

The Chlorination of Gold Ores.

The Chlorination of Gold Ores. By Mr. Donald Clark, M.M.E., B.C.E. The ideal method for extracting fine gold would be to dis-solve out the gold with some solvent which would not attack other minerals present. The solvents known 6o years ago were chlorine, bromine, and cyanide of potassium. Yet in spite of this knowledge it was only comparatively recently that such solvents were successfully
