Iron ore mining is the process of extracting iron from its natural form, which is found in rocks and minerals. The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can ...

For the deposit investigated, it was found that the mine is likely to generate final product of MT of Lump Ore (+ 10 mm − 150 mm) and Fines Ore MT (− 10 mm) during the life of the mine. The NPV is found to be highly sensitive to the price of Fine ore as quantity of fines in total ore body is around 70%.
