  • Processes for phosphorus removal from iron ore a review

    2.2.1 Chemical Processes. Acid leaching has been considered as an alternative to flotation for removing phosphorus from iron ore. Technologically, the leaching process is a simpler way to treat the fineparticle sinter feed without the restrictions that are necessary in flotation.

  • Creating Steel HowStuffWorks

    Impurities like silica, phosphorous and sulfur weaken steel tremendously, so they must be eliminated. The advantage of steel over iron is greatly improved strength. The openhearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an openhearth furnace. It is heated to about 1,600 degrees F (871

  • Iron ore Wikipedia

    Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.

  • Increasing Iron and Reducing Phosphorus Grades of Magnetic

    Highphosphorus oolitic iron ore, treated by suspended flash magnetic roasting, contained 42.73% iron (mainly present as magnetite) and 0.93% phosphorus (present as collophane). Lowintensity magnetic separation (LIMS) was combined with reverse flotation to increase the iron and reduce the phosphorus contents of the roasted product.
