    Currently most of the high grade iron ore mined in the world comes from large deposits of massive hematite rock formed by the in situ enrichment of a protore already enriched in iron, most commonly a banded iron formation (BIF). Another type of high-grade deposit is pisolitic limonite/goethite ore formed in ancient river channels. One of the primary forms of iron ore is hematite, or iron oxide (Fe2O3).

    Iron-rich sedimentary rocks Wikipedia

    There are four facies types associated with iron-rich sedimentary rocks: oxide-, silicate-, carbonate-, and sulfide-facies. These facies correspond to water depth in a marine environment. Oxide-facies are precipitated under the most oxidizing conditions. Silicate- and carbonate-facies are precipitated under intermediate redox conditions.

    However, for classification and evaluation of quality, the raw iron ores can be divided into three basic classes depending on the total Fe content: (i) high-grade iron ores with a total Fe content above 65%, (ii) medium- or average-grade ores with varied Fe contents in the range between 62–64%, and (iii) low-grade ores with Fe contents below 58% [2–5].

    09-03-2018· Due to high dilution and low recovery, block caving should be used for large, steep, and low-grade ore bodies. Due to the low selectivity of the block caving method, it is suitable for ores that have uniform grade distribution. Also, high grade that does not cave well requires fracturing with explosives, which can increase developmental costs.
