History of the iron and steel industry in the United States

Because iron and steel-making at the time consumed more coal than iron ore the steel mills moved closer to the coal mines to minimize transportation costs A problem of coke was that it carried impurities such as sulfur which degraded the quality of the steel

flotation in mining iron ore

Jun 30 2019 Iron ore mining often focuses on looking for hematite deposits known as red iron ore and magnetite as they have naturally weak magnetic fields that aid in their purification Hematite however responds better to the flotation process in iron ore beneficiation than magnetite so it is the preferred type of ore

Environmental impact of iron ore mining

Mining and processing If the ore contains less than 60 percent iron it is usually beneficiated to an iron-ore concentrate typically containing greater than 60 percent iron This is done by separating the iron minerals from the valueless minerals usually by magnetic gravity or froth floatation

Froth flotation

For froth flotation the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic requiring little or no addition of collector) The particular chemical depends on the nature of the mineral to be recovered and perhaps the natures of those that are not wanted
