Basics of mineral processing
· 37 Properties of mass play a major role in Mineral processing All deposits of minerals, rock or ores have different hardness depending on the chemical composition and the geological environment. Size and hardness 38. 38 All operations have different process environments due to mineral hardness and size range.
· Mineral processing. Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
