iron ore mining 3 hematite ore

What isiron ore?Ironores are rocks and minerals from which metallicironcan be extracted. There are four main types ofiron oredeposit: massivehematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron arehematite Fe 2 O 3, and magnetite,Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

Increasingiron oredemand, coupled with the depletion of high-gradehematiteores in the United States, after World War II led to development of lower-gradeiron oresources, principally the utilization of magnetite and taconite.Iron-ore miningmethods vary by the type oforebeing mined.
