    Geology and Reserves of The Kiruna MineMining and Processing at KirunaCompleted and Ongoing Projects at The Kiruna MineContractors Involved with The Kiruna Mine Deepening ProjectThe Kiruna orebody was formed at around 1,600Ma following intense volcanic activity with the precipitation of iron-rich solutions on to a syenite porphyry footwall. The ore bed was then covered by further volcanic deposits (quartz porphyry) and sedimentary rocks before being tilted to its current dip of 50-60°. The ore contains a very pure magnetite-apatite mix, containing more than 60% ironand an average of 0.9% phosphorus. Black See more on mining-technology

  • mining - Underground mining Britannica

    Prior to the production of ore, a certain capital investment in mine development work is required. In open-pit mines this consists of building access roads and stripping the overlying waste material in order to expose the ore and establish the initial bench geometries. For an underground mine the development stage is considerably more complicated.
