How Can We Minimise The Impurity Phosphorus From Iron Ore

impurities removal from high carbon ferrochromium by,submit arc furnaces and can be represented as a reduction of ores materials by coke. as a result of the reduction process the metal contains about 8% of carbon and 1–4% of silicon. besides depending on the quality of initial materials, the metal can have heightened impurity levels: titanium, phosphorus, sulphur, etc. some customers require.analysis: australian iron ore fines' alumina, phosphorus,'most chinese mills, especially those in north china, are able to use higher phosphorous ores in blast furnaces and it will not impact the daily production much. however, higher impurities lead to lower value-in-use for the iron ore fines, which should be reflected ultimately in the price,' one steel mill procurement source said..characterisation of phosphorus and other impurities in,abstract. phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes, forming iron phosphides that make steel brittle. excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.07–0.08 wt-% p on the iron ore feed..extraction of iron from its ores, iron dressing, reduction,roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, it is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus. roasting of iron is very important in the ore dressing process but this process pollutes the environment, ore dressing is important for iron ores before their reduction to.
