Iron Ore is the ore
of Iron =)
and is also known as haematite
. It is red
and turns everything
around it red. Usually large deposits
of Iron Ore are denoted by huge red patches of the earth
or large patches or rust on your old bike =p. Iron Ore is converted into Iron using a blast furnace
to reduce it with carbon
according to the following equations:
C(s) + O2(g) -> CO2(g)
CO2(g) + C(s) -> 2CO(g)
Fe2O3(s) + 3CO(g) -> 3CO2 + 2Fe(l)
The iron is a liquid because of the fact that it is extremely hot. The iron is usually piped out the bottom of the furnace and refined some more to get steel and other alloys. Iron Ore is also slightly magnetic.
According to my chemistry book the world iron ore requirements are about 1000 million tonnes a year and Australia produces about 10% of that.
Iron Ore can also be found as 2Fe2O3.3H2O which is a yellow-brown ore.
