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.

Why high
25.03.2021Higher-purity iron ores generate less slag when consumed in blast furnaces, allowing coke rates to be kept lower, while direct-charge ores such as lump and pellet also lessen the consumption of coke breeze in the sintering process. Using higher-grade iron ore feedstocks is therefore preferable for mills when coking coal prices are high.
