    The way a given ore is described in terms of the enrichment. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal. In General, the minimum concentration factor required for profitable mining is inversely porportional to the average crustal concentration

    Hematite can also occur without water, however, usually as the result of volcanic activity. Clay-sized hematite crystals can also occur as a secondary mineral formed by weathering processes in soil, and along with other iron oxides or oxyhydroxides such as goethite, is responsible for the red color of many tropical, ancient, or otherwise highly weathered soils.

    Processes For Beneficiation Of Iron Ores – IspatGuru

    Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth’s crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.

    Difference Between Magnetite And Hematite L Magnetite Vs Hematite

    Magnetite and hematite are important oxides of iron. Though there are several differences between them, the key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state.
