  • Reuse of iron ore mineral wastes in civil engineering

    2008 9 1· Removal of overburden to access the ore can pose major problems in storage and reclamation The stripping ratio (wastetoore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions The iron ore is predominantly mined by opencast mining throughout the country2014 3 14· To gain access to the iron ore deposit within an area, it is often necessary to mine through or remove waste material (also known as overburden) which is not of an interest The total movement of ore and waste constitutes the mining processMining of Iron Ores – IspatGuru2017 10 25· Management of the stepwise processing of ironore waste in mining regions ensures rational resource utilization by introducing wastefree and lowwaste technologies, with subsequent conversion of the reclaimed land to recreation areas A procedure that may be used by operational enterprises has been developed, including the sequence of operational steps, charts for tailingsSystematic processing of ironore waste in mining regions |

    The iron ore is separated from the taconite using magnetism The remaining rock is waste material and is dumped into tailings basins The taconite powder with the iron in it is called concentrate Pellets The concentrate (the wet taconite powder) is rolled with clay inside large rotating cylindersWaste rock is the rock that is excavated to reach the ore The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks The ratio between waste rock and oreLecture 4: Mining waste SGU2021 7 23· Mining iron ore is a highvolume, lowmargin business, as the value of iron is significantly lower than base metals It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight shipIron ore Wikipedia
