Benefits of Mineral Beneficiation. The benefits of mineral beneficiation or ore dressing are as follows: High volume production in lesser time. Increases the metal content of the ore. Decreases the gangue content to get the most out of the ore. It provides raw materials that support the country's infrastructure and economy.
