  • How to Precipitate Mercury from Gold Silver Cyanide Leach

    In mercury precipitation tests in a ball mill, CaS was added to the slurry in the mill along with cyanide and lime. The slurry mixture was ground for 45 min, washed from the ball mill with water, and leached for periods of up to 24 h at 25 pct solids. Additional mercury precipitation tests were conducted by adding CaS directly to the pregnant cyanide leach slurry, followed by three-stage CIP ...

  • Sodium cyanide - Wikipedia

    Sodium cyanide is an inorganic 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: NaCN + H 2 SO 4 → HCN ...
