Flowsheet Options

For the processing of a refractory gold/silver concentrate, the pH of the oxidative leach is held at 5.5 by the continual addition of limestone slurry to ensure complete oxidation of the sulphur to sulphate. The oxidised residue can then be fed directly to a cyanide leach plant for precious metals recovery.
