magnetic concentarted iron ore

  • What Is Iron Ore Beneficiation? (with pictures)

    Jun 30, 2019Methods such as screening, crushing, and grinding of iron ore are often used in various ways to purify it, along with several stages of magnetic separation. 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%.

  • Iron Ore Statistics and Information

    Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

    Once again, the magnetic separators grab the iron and discard the silica and sand. Thus, the ore is concentrated by removing the waste materials. The concentrate from the separators is pumped to fine screening. The oversize material is returned to the balls mills, while the undersize (with the most impurities removed) becomes the final concentrate.

  • Iron Ore

    The typical magnetite iron ore concentrate has less than 0.1% phosphorus, 3-7% silica and less than 3% aluminium. The grain size of the magnetite and its degree of comingling with the silica groundmass determine the grind size to which the rock must be reduced to enable efficient magnetic separation to provide a high purity magnetite concentrate.
