The process at Millsell involves six stages, the first of which is the obviously the mining that produces the tailings. The mines, in upgrading the chromite content of their ore, produce a tailings stream that contains the majority of the PGMs of the ROM chrome ores. It is these chrome ores with elevated levels of PGMs that are treated.
