Minerals.

The hardness of a mineral is determined by Moh's Scale of Hardness (1-10) If a mineral can scratch glass it is said to have a hardness of 5.5 or greater. If it does not scratch glass it is said to be <5.5. A mineral will only scratch another mineral if it is harder than the other mineral.

Mineral Prossesing

subsequent operations will be termed as Ore Dressing or Mineral Beneficiation. So mineral dressing or ore dressing is commonly regarded as processing of raw ores to yield marketable products by such physical means those do not destroy the physical and chemical identity of the ore. Economic Justification of Mineral Dressing: 1.

Mineral dressing (= Orebeneficiation)

Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ore minerals and a tailing (discard) containing the bulk of the gangue minerals.
