  • Iron Ore Mining | Techniques | Metal Extraction

    Iron ore mining techniques differ by the type of ore that is being hauled out There are 4 types of iron ore deposits that is being worked on at present, Based on the mineralogy and geology of the ore deposits HOW IS IRON OBTAINED? 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· Mining techniques usually consist of two types based on excavation methods These are surface mining and underground mining (sub surface mining) Iron ore is almost exclusively mined by surface operations The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods However a few underground iron oreMining of Iron Ores – IspatGuru· The deep mining of iron ore is unusual in the modern era, but in northern Sweden, ore is mined from considerable depth largely aided by the application of automation and remote control equipment Kiruna has been chosen as the example for a more detailed review of underground techniques However, in order to provide an historical context of the early smaller scale of iron oreIron ore extraction techniques ScienceDirect
