CHAPTER 1 MINERAL DRESSING

The ore lumps from the mines have the lump size of 10 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
