» iron concentrate price on market

Iron ore processing is divided into two categories based on the product: production of granulated iron ore and production of iron ore concentrate. Production of granulated iron ore is done dry and without water. Then, using physical separation methods (magnetic method), high-grade iron ore is separated from low-grade tailings.

BENEFICIATION OF BOREHOLE IRON ORE SAMPLES THROUGH …

It is a low-grade type of ore sample (±35% Fe) with high silica and calcium content (±36%). Based on the fact, that there are appreciable differences in magnetic susceptibility between the desired iron minerals and the gangue minerals, hence, it was suggested that multi-stages magnetic separation may be useful to concentrate this type of ore.
