1. Introduction. The leaching of gold bearing ores with cyanide has been reported since 1889 in New Zealand and South Africa (Dorr and Bosqui, 1950).Despite recent attempts to develop alternative extraction procedures such as the use of thiocyanate, ammonia, thiourea and thiosulphate (Hilson and Monhemius, 2006), the cyanidation process still remains the preferred method as it is economically ...

Free cyanide must be present in order for the zinc to dissolve rapidly in a cyanide solution. Therefore it is typical to add NaCN and lead nitrate with the zinc to ensure the presence of free CN. As gold (along with silver) is precipitated with zinc, this high-solids mixture is then processed with a filter press to capture the precipitated precious metals with a purity that will range between ...
