Gold recovery techniques from cyanide solutions. CN Process . CN process can be used for removing gold from gold plated electronic waste like connectors, fingers, jewellery and any other stuff which has gold polish on it. For the recovery of gold through this method one has to use commercial grade sodium CN (NaCN) because is less risky and cheap than potassium CN. Some people think that NaCN

Potassium cyanide Wikipedia

In gold mining, KCN forms the water-soluble salt potassium gold cyanide (or gold potassium cyanide) and potassium hydroxide from gold metal in the presence of oxygen (usually from the surrounding air) and water: 4 Au + 8 KCN + O 2 + 2 H 2 O → 4 K[Au(CN) 2] + 4 KOH. A similar process uses NaCN to produce sodium gold cyanide (NaAu(CN 2)). Toxicity. Potassium cyanide is a potent

Cyanide Chemistry & Gold Extraction

In the cyanide-solution, the oxygen and the cyanide of potassium may exist side by side in solution (as experiment shows) without sensible action on each other, unless the presence of gold determines the Elsner reaction at the point where oxygen, water, gold, and cyanide of potassium meet. If a thorough utilization of the cyanide is desired, the action of the oxidizer should be such that the

Effect of Potassium Cyanide on Gold & Metals

Metallurgists found that gold leaf would not dissolve in a solution of potassium cyanide from which the air had been expelled by the passage of a current of hydrogen, and that the addition, under these circumstance, of either potassium dichromate, chromate, chlorate, perchlorate, nitrate, or nitrite or of ferric hydrate or bleaching powder, did not enable the gold to dissolve. The addition of
