If the resource material contains significant pyrite (around 0.8–1% sulfide sulfur), 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.
