A secondary crusher, known as a roll-crusher, may also be used to reduce the size of the ore even further. Stage 2 – Scrubbing. In this stage, the ore are scrubbed to remove loose excess material and is screened. Material smaller than 1.5mm is discarded because it is too costly to extract diamonds from such a small piece of ore.
