Overview of Mineral Processing Methods

The first process that most of the ores or minerals undergo after they leave any mine is mineral processing or mineral/ ore dressing. It is a process of ore preparation milling and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals.
