  • Sodium cyanide -

    Sodium cyanide -

    Sodium is a poisonous compound with the formula Na C N.It is a white, water-soluble solid. 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 :

    Gold cyanidation -

    The Inco process can typically lower cyanide concentrations to below 50 mg/L, whereas the Caros acid process can lower to between 10 and 50 mg/L, with the lower concentrations achievable in solution streams rather than slurries. Caros acid – peroxomonosulfuric acid H 2 SO 5 - converts cyanide to cyanate. Cyanate then hydrolyses to ammonium and carbonate ions.
