Cyanide Process

The gold is mixed with the sodium cyanide which leads to the following Elsener''s equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added into the ore containing the gold.

POTASSIUM CYANIDE PILL

The lethal dose for potassium cyanide is 200-300 mg.The toxicity of Potassium Cyanide Pills when ingested depends on the acidity of the stomach, because it must react with an acid to become hydrogen cyanide, the deadly form of cyanide. Grigori Rasputin may have survived a potassium cyanide poisoning because his stomach acidity was unusually low.

Separation of Gold metal from Potassium Gold Cyanide salt

 · In its purist form, which is usually used in acid gold baths, the PGC will contain about 68.3% gold. If it is used for cyanide baths, it might also contain some potassium cyanide, which would lower the gold percentage. If it is used for acid baths, it could also contain a little nickel or cobalt and will have a green or pink color.

molecular hydrogen cyanide (HCN) or cyanide ion (CN-). Cyanide salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are colorless crystalline solids that have a slight odor of bitter almonds in damp air. These salts readily dissolve in water and are converted to the uncharged hydrogen cyanide (HCN) molecule in most natural waters.
