    Iron ore raw materials pany

    Iron ore raw materials of the first kind are ready to be used in blast furnaces to produce pig iron, while materials of the second kind are used to produce agglomerated raw materials. Natural raw materials include concentrates, direct shipping ores and sinter ores. Concentrate is mainly produced byic separation of fine low grade ore. Iron recovery in concentrates is on average about 80

    Metal Profile: Iron Properties and Characteristics

    12/01/2020· The limestone mixes with impurities in the iron to form slag. Slag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production.

    Iron Production Chemistry LibreTexts

    15/08/2020· 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.

    Metalwork Materials

    Iron Ore is smelted in the Blast Furnace in order to remove unwanted impurities such as rocks, clay and sand, and also to seperate the Iron from the Oxygen. The result is Iron which is about 95 pure. The remaining impurities are other elements which can be removed later if necessary. A Blast Furnace is about 100ft. high and produces abut 1000 tons of molten Iron a day. It is made from steel

    Creating Steel HowStuffWorks

    ­Steel is iron that has most of the impurities removed. Steel also has a consistent concentration of carbon throughout 0.5 to 1.5 percent. Impurities like silica, phosphorous and sulfur weaken steel tremendously, so they must be eliminated. The advantage of steel over iron is greatly improved strength.
