Uranium is a naturally occurring radioactive element very widely distributed throughout the earth’s crust [ 1 ]. It is present in varied concentration in almost all types of rocks, natural water including sea water, and living organisms. The average concentration of uranium in the earth’s crust is about 2.76 ppm in rocks [ 2 ], less than 1 ...

5 天之前 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.
