Hematite is a black, grey or reddish-coloured mineral which is mined as the main source of iron. Hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as "Direct Shipping Ore" or "DSO" because it is mined and beneficiated using a relatively simple crushing and screening

processes for obtaining iron mineral hematite. Hematite Processing by Flotation. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with "Sub-A" Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.
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. What
Arrium (previously OneSteel) initiated a desktop study into the performance of its hematite ore beneficiation plant in early 2022. The beneficiation plant utilises jig concentrators and spirals to upgrade low-grade hematite recovered during mining at the Iron Duke (ID) mine site located 60 km south-west of Whyalla. The study, conducted in conjunction with Mineral Technologies, identified a
Therefore, low-grade hematite ores must be treated by mineral processing methods (, flotation and magnetic separation) to obtain the iron Hematite an overview ScienceDirect Topics Low-grade hematite ores need to be upgraded to achieve the required iron content, which involves more complicated ore beneficiation processes.
