What Is Iron Ore Beneficiation? (with pictures)

Ray Hawk Raw iron ore has to be purified for use. Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content.The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.

Beneficiation - Wikipedia

Process removing the gangue minerals of an ore resulting in a higher grade product. 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 ( ore concentrate) and a waste stream ( tailings ).

Quality starts with the ore — Metals Magazine

In the past, the primary focus was placed on enhancing downstream production processes, however, upstream processes, in particular beneficiation, today offer many opportunities for profitable improvements. By enhancing the quality of lower-grade raw materials through beneficiation, downstream processes also become more viable.
