concentration or dressing of the ore.

Concentration of Ore Ore Dressing. Ore is a impure metal containing large amount of sand and rocky material. The impurities like sand, rocky materials, limestone, mica etc present in the ore is called gangue or matrix. The substance added flux to the ore to remove the matrix results in the formation of a fusible compound called slag.

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.
