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. This is accomplished by the method of pyrometallurgy, a high temperature process. The high

Phosphorus Impurities Iron Ore. Phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes forming iron phosphides that make steel brittle. Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.070.08 wt- P on the iron ore.

Impurities in Pig Iron and Their Effects 1. Phosphorous. The quantity of phosphorous present in pig iron varies from 0.1 to 2.0%. It combines with iron to form Fe3P which embrittles cast iron. Phosphorous is introduced into iron from phosphate in the ore. Phosphates get reduced in the reducing atmosphere in the blast furnace and phosphorous is formed. This phosphorous combines with iron to

Then, impurities are removed and alloying elements are added. The steel is then cast, cooled and rolled for use in finished products. Once the iron ore is processed, a stacker builds a stockpile in the stockyards. Train loading. When ready for transportation, a reclaimer picks up the ore from the stockpiles and conveys it to train load out facilities. Rail. Trains transport the iron ore to
