Editor's note: Some chemicals in this database contain more information than others due to the original reason this information was collected and how the compilation was accomplished. While working with material safety data sheets (MSDS), I found that manufacturers sometimes used obscure names for constituent chemicals and I didn't always have a good idea of what I was dealing with.

Iron Production

Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.

Iron deficiency is the most common nutritional deficiency in the United States and worldwide, affecting older infants, young children, and women of childbearing age. The third National Health and Nutrition Examination Surveyidentified about% of childrenyears of age as iron-deficient.Infants are born with stores of iron roughly proportional to birth weight.

The Extraction of Iron

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
