Most of the mines employ twostage processing plants, with the first stage processing the raw coal to yield an export product and the second stage reprocessing the rejects from the first stage at a higher relative density to produce a thermal coal for Eskom. There are also a growing number of small plants that only produce coal for Eskom.
