Mining of Iron Ores – IspatGuru

14.03.2014  Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). The process ...

Iron: From mythical to mundane - The Roots of Progress

22.10.2019  Of course, iron ore is not pure; it can contain impurities such as sulfur and phosphorous. Some of the impurities are separated out during smelting, forming a waste product called “slag”. This is the purpose of adding lime: it acts as a “flux”, that is, a material that helps separate out the slag. A small amount of slag remains in the bloom, however, so the next thing to do is to pound ...
