How to Use Bleach on Gold Ore to Remove Gold | Sciencing

Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the oreHow To Dissolve Gold From Ore,How To Dissolve Gold From Ore By Acid archedyl. In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing. Dissolving Gold and Precipitating Gold Pyrometallurgy,How to Remove Gold from Ore | Sapling,Crush and mill the gold ore to dust like particles. Ore is put into the crusher, which breaks it up. Water is added during the process which, when mixed to the ore particles, creates a pulp. The ore in the pulp is then ground into smaller particles and pulverized into a ball mill. Step 2 Classification process begins, where the ground up ore pieces are separated by sizes. Large
