Burnishing is a chipless machining method which cold works the metal without cutting or abrading the surface. It removes no metal but rather compresses, or "irons-out" the peaks of a metal surface into the valleys, generating a dense and uniform surface. Roller burnishing improves surface finish and results in dimensional accuracy.

Micro-cracking improves mineral liberation The high pressure of HPGR's "bed-breakage" creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time.
