    Hematite is often cheaper to process than other forms of iron ore as it generally does not require beneficiation due to its higher iron content. However, hematite ores may contain higher concentrations of contaminant elements (such as phosphorus, alumina and silica) and may therefore need to be blended prior to smelting. Export grade hematite ores generally grade above 60% iron content.
