      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.

    • Sodium cyanide

      Sodium cyanide is a poisonous compound with the formula Na C N.It is a white, water soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide

      A process that can be used to produce NaCN is provided. The process comprises contacting hydrogen cyanide with sodium hydroxide solution to produce a NaCN solution and crystallizing the NaCN solution wherein the process is carried out in the presence of an acid or a metal salt of the acid in which the acid has a pKa 4.8. The NaCN crystals can be separated from the slurry and dried.

    • How to Prepare and Storage of Cyanide Solution

      The cyanide is usually dissolved in a little water before being added to the stock solution, as the amount of KCy present is more easily determined in a strong solution than in any other form. A special dissolving vat of small size is often provided and is placed at a higher level than the large vats used for the storage of the stock solution. High grade cyanide is now largely used containing
