After optimizing the experimental conditions, it was demonstrated that in addition to sulfur, more than 80% of phosphorus, another important impurity, was also removed from the iron ore concentrate. In addition, one of the major advantages of our proposed method was the transformation of mineral pyrites to useful byproducts such as elemental ...

Phosphorus Removal from Goethitic Iron Ore with a Low

removing phosphorus from molten iron exist,2) a number of factors such as financial penalties and market access make it attractive to ensure that phosphorus is removed from the iron ore prior to its use in smelting. Market specifications for phosphorus in iron ore exported from Australia are typically 0.075% P. 3) The bulk of produc-

The iron produced in a blast furnace contains significant

The iron content of iron ore can be determined by dissolving the iron ore in HCl. The dissolved Fe3+ (aq) from the iron ore is then reduced to Fe2+. e- + Fe3 In the Mond process for the purification of nickel, carbon monoxide is reacted with heated nickel to produce N i ( C O ) 4 , which is a gas and can therefore be separated from solid impurities: N i ( s ) + 4 C O ( g ) N i (
