A practical guide to re-treatment of gold processing residues
If the resource material contains significant pyrite (around 0.8–1% sulphide sulphur) some of the gold is liable to be associated with the pyrite. If this pyritic gold is simply allowed to follow a slime processing circuit as described above it will report directly to the CIL plant where two undesirable impacts will arise.
