phosphorus impurity in iron ore Removal of phosphorus from iron ores by Removal of phosphorus from iron ores by gravity or heavy media separation
the iron ore is reduced by carbon then this reduction absorbs a lot of heat so this is The phosphorus level quickly decreases during the reactions the phosphorus level in the hot metal increases back This is due to consumption of FetO in the slag by carbon Due to decarburized reactions so during the steelmaking reactions phosphorus level
