    The barren pulp from the CIL circuit and any cyanide containing spillage are pumped to the cyanide destruction circuit via a carbon safety screen, to detect any leakage of carbon from the last tank. The barren pulp is combined with the non-cyanide-containing tailings from the parallel flotation circuit. The residual cyanide content is destroyed in two reactors by means of the INCO/SO2/Air process before it
