The tailings are contained by an embankment. Also visible in the foreground is a pile of waste rock, which is non-ore rock that was mined in order to access the ore. Although this waste rock contains little or no ore minerals, at many mines it contains up to a few percent pyrite. The tailings and the waste rock at most mines are an ...

While waste rock fragments and other minerals are washed away by flowing water and sprayers, diamonds resist being wetted and adhere to the greased surface instead. The diamond-laden grease is scraped off the table, boiled in water to remove the grease and the resultant screened particles cleaned using a solvent degreasing machine.

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
