The concentration of ore, also known as ore enrichment, is the process of removing gangue particles from ore in order to enhance the percentage of metal in the ore. The difference in physical or chemical properties of the ore and the impurities determines the procedures used to remove impurities from the ores.

Mineral 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 (low-value) minerals that surround them in order to produce a concentrate made up of useful minerals.

This process of removal of impurities from the ore is often referred to as concentration, dressing, or beneficiation of ores. The physical and chemical properties of gangue determine the process of ore enrichment. Various methods of concentration of ore are: Hand Picking. Hydraulic Washing. Froth Floatation Process. Magnetic Separation ...
