Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag.

What is mineral beneficiation? Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes.
