Most chemistry text books cover the blast furnace process. Nearly all iron produced commercially is used in the steel industry and made using a blast furnace. Other routes to small samples of pure iron include the reduction of iron oxide, Fe 2O 3, with hyrogen, H 2. The Fe(CO) 5 is a volatile oily complex which is easily flushed from the reaction vessel leaving the impurities behind. The carbonyl decomposes on heatingto about 250☌ to form pure iron powder. The intermediate in this process is iron pentacarbonyl, Fe(CO) 5. Small amounts of pure iron can be made through the purification of crude iron with carbon monoxide. Isolation: it is not normally necessary to make iron in the laboratory as it is available commercially. This sample is from The Elements Collection, an attractive and safely packaged collection of the 92 naturally occurring elements that is available for sale. Do not attempt this reaction unless are a professionally qualified chemist and you have carried out a legally satisfactory hazard assessment.
The picture above shows the result from adding iron filings to a burning mixture of potassium chlorate and sucrose. Iron filings salts cause sparks in flames. Iron metal is a silvery, lustrous metal which has important magnetic properties. The pure metal is very reactive chemically, and rapidly corrodes, especially in moist air or at elevated temperatures. The pure metal is not often encountered in commerce, but is usually alloyed with carbon or other metals. Iron is a vital constituent of plant and animal life, and is the key component of haemoglobin. It is found in the sun and many types of stars in considerable quantity.

In those cases, the origin of the symbol used is given.
A very few elements have symbols which appear to have no relationship with their names.
In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. Most chemical elements are represented symbolically by two letters, generally the first two in their name.
