WEBMineral processing is the first step for ore once it leaves the mine. The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals from the gangue (lowvalue) minerals that surround them in order to produce a concentrate made up of useful minerals.
