We achieve a concentrated ore with a high percentage of metal by eliminating these impurities. 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 …
