What Is Iron Ore Beneficiation? (with pictures)

Aug 08, 2019The 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%. Low-grade iron ore includes all mixtures below 62% iron concentration,

Iron and steel

Aug 12, 2018Types of iron. Pure iron is too soft and reactive to be of much real use, so most of the iron we tend to use for everyday purposes is actually in the form of iron alloys: iron mixed with other elements (especially carbon) to make stronger, more resilient forms of the metal including steel. Broadly speaking, steel is an alloy of iron that

In mining it would naturally be impractical to free the high grade ore entirely from an admixture of earth and pebbles of lower grade ore and this would somewhat reduce the metallic product, but this reduction would presumably be more than compensated, in most cases, by a reduced cost of mining and transportation, since in general this class of ore lies in more favorable positions than the other.
