Mineral processing | metallurgy | Britannica

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.The primary operations are comminution and concentration, but there are other important operations ...
