Beneficiation of Iron Ore
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500

What is iron ore beneficiation?
The composition of the ore is relatively complex, and the grain size of the ore is mostly finer, which causes certain difficulties in beneficiation. . Technically speaking, there is an urgent need for advanced technology, advanced technology and advanced equipment to promote the efficient development and utilization of poor iron ore resources.

What Is Iron Ore Beneficiation? (with pictures)
Iron ore is smelted after going through beneficiation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed. High-grade iron ore must have a concentration of 65% iron or higher, and medium grade of 62% to 65%.
