Iron Ore Beneficiation

A premium high-grade, high recovery iron ore product has been generated with almost no slime content from the received feed (i.e. low silicates and other contaminates). The work has also been able to achieve high shear induced lift that is needed to reject coarser gangue material and retain finer high density material across a particle size range from 0.125 to 1.0 mm.

Low grade Iron Ore Beneficiation and the Process of Jigging –

2021/9/25Since the iron ores consist of several compositions, mineralogies, shapes, and sizes, so there is no 'one size fits all' approach to the beneficiation of iron ore. Most of the 'run-of-mine' (ROM) iron ore contain a large percentage of other materials which need to be removed through the process of beneficiation before the ore attains the specifications needed for its use.
