Processing Gold by Cyanidation Leaching

Processing Heap Leachable Gold Ore by Cyanidation Oxide ore (low grades) will be unloaded on the heap leach PAD. Lime must be added during the discharge in order to control pH. Harvesting must be performed after the ore discharge is completed in order to avoid compaction caused by the trucks during the leach cell construction. After the leach cell is harvested, the irrigation system shall be

(0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90–120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces a small volume of solution with a high gold concentration. The gold is recovered from this solution by

How to Use Bleach on Gold Ore to Remove Gold Sciencing

Apr 24, 2017· 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 that dissolves gold from gold ore.
