process using caustic lye in gold miningri

Sodium Cyanide Solution

Using sodium cyanide solution also eliminates the use of chemicals, such as caustic soda, to maintain a stable pH level when dissolving solid sodium cyanide. Water quality, in particular salinity, can significantly destabilise the pH balance in the dissolution process. Get price

How to Use Bleach on Gold Ore to Remove Gold

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. Get price

Using Mercury

Now we have a gold particle with a layer of mercury sticking to its surface because of the very high surface tension of mercury. The mercury will now continue to dissolve in the gold and penetrate deeper into the particle. This process, however, is rather slow and the deeper it penetrates the slower it goes. Get price

Streamlining Clean

No matter what the size or nature of our mining operations, we all have one common procedure to deal with—the cleaning up of our concentrates. Sometimes, the process of separating the gold from the other sand and gravel is a tedious task. But, there is a way to make it relatively quick and easy. Get price

Demonstration of the CESL Gold Process

The copper is initially recovered from the concentrate using the CESL Copper Process (Robinson, Mayhew, Jones, Murray, 2011). The gold and silver remain in the leach residue, which is subsequently treated using the CESL Gold Process. The CESL Gold Process consists of the following main steps as illustrated in the figure below. Get price
