Extraction of Iron. Extraction of iron from its ore is the third and the penultimate process in the Metallurgy. The extraction of metals and its isolation occurs over a few major steps:
The steelmaking process starts with the processing of iron ore. The rock containing iron ore is ground and the ore is extracted using magnetic rollers. Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast ...
The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from low-grade iron ore requires a long process of mining, crushing,
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. The remaining rock is waste material and is dumped into tailings basins.
