Beneficiation processes - Rio TintoMining process. A large artificial freshwater pond is created in the dunes, on which floats the dredger and concentrator plant. While the dredge removes the material from the front end of the pond, the tailings generated by the separation process is stacked at the back; as a result the pond continuously moves in a forward.beneficiation processes,BENEFICIATIONBeneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic.

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity.
