  • Iron Ore Mining Techniques Metal Extraction

    Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the iron oxide in a blast furnace to give iron as a result since iron ores consists of the element iron combined with other elements, mostly oxygen. Haematite and magnetite are the most commonly found iron ore minerals.

    Mar 14, 2014  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 of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.

    MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
