How iron is made
The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.

Extraction of iron compounds from wood from the Vasa
In 2000, salt precipitates were found on surfaces of the Swedish warship Vasa, accompanied by low pH values, partly as a result of oxidation of accumulated sulfur compounds. One hypothesis is that oxidation of the sulfur compounds was catalysed by the large amounts of diverse iron compounds present in the wood. It is therefore of interest to develop a method to extract the iron compounds and ...
