Iron Ore Processes and History

Iron Ore Processes and History

Intro

An ore also is a mixture of one or more minerals. We distinguish ore

from rock in that a valuable and/or useful material can be mined or

extracted from the ore. This material often is a metal. Iron ore, is

mined for its iron content. Mining companies sell the ore to

manufacturers who extract the iron and use it in producing iron and

steel products. The portion of the ore that is not iron is considered

a waste or by-product. Even though it is considered a waste of the

iron process, the by-product may be useful in some other process.

Firstly, iron is quite magnetic. Ores can be located by magnetic

sensing akin to backyard metal detectors, and possibly even harvested,

unoxidised iron at least, with simple electromagnets.

Underground mining is achieved by sinking shafts to the appropriate

levels and then driving horizontal tunnels, called adits, to reach the

ore. Underground mining is, however, relatively expensive and is

generally limited to rich ores.

Iron compounds are used as a colourant in glasses, which look to have

a tremendous importance in lunar construction, manufacturing, and

export.

==================

Smelting is a way of getting metals from the rocks in which they exist

in their natural form. These rocks are often known as ores. These ores

are heated to a high temperature in an oven or a kiln, so that the

metal in them melts and flows out of them. This molten metal is then

collected from the base of the oven.

A furnace for smelting ironstone at high temperatures beyond the

melting point of Iron (Fe, 1540°C) is used. These furnaces are us...

partner Charles Bage. It took over a year to build and was a first in

structural engineering; it was the first iron-framed building in the

world. It's the mill's design that makes it such a groundbreaking

building, because it was the first building in the world to be

constructed around an iron frame. Charles Bage developed a perfectly

valid method of designing cast iron beams on the basis of tests and

Galileo's bending theory.

This system was later taken up and employed to construct tall

buildings all over the world. Essentially this structure represents

the birth of the skyscraper, most notably adopted during the

reconstruction of Chicago almost a century later.
