Higher-purity iron ores generate less slag when consumed in blast furnaces, allowing coke rates to be kept lower, while direct-charge ores such as lump and pellet also lessen the consumption of coke breeze in the sintering process. Using higher-grade iron ore feedstocks is therefore preferable for mills when coking coal prices are high.
Low-grade ore (< 60% Fe content) undergoes multiple processing steps to increase the overall iron content. These include crushing, screening, milling, flotation or magnetic separation, followed by filtering and drying. These processes produce fines with an iron content greater than 60% and smaller than 0.1 mm.
Some factors have contributed to this fact as follows: the depletion of high grade iron ore reserves, the great Chinese iron ore demand, the …
