Definition Iron/Iron Ore
Iron ores are mixtures of chemical compounds of the
iron with rocks
The chemical compounds of the iron in the iron ore are
essentially ferric oxides, i.e. chemical compounds of
the iron with oxygen, or iron carbonates
Iron Ore sources at Lahn area
In Germany there are some iron ore occurrences,
e.g. in the Lahn Dill area.
The ore reserves become world-wide estimated on
over 115 billion tons ore.
Particularly the Lahn Dill area was shaped by
mining industry.
From the early Middle Ages to the second half of
20th Century were this still the most important
locations in completely Germany.
Dismantling methods of
Iron Ore
Dismantling methods:
In principle one differentiates between two techniques:
Over days: The raw material is promoted by excavation
to open pits.
Under days: Promotion by lugs underground put on or
pits in the so-called mountains (mining industry).
Processing of Iron Ore
After promotion of the iron ores these are
often already cleaned in the first stage of the
processing.
Afterwards the large ore must be cut up.This
work by cone or jaw crushers one settles.
After that the iron ore is separated over
magnetic separators and converted to iron ore
pellets.
