Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
Hematite turns into magnetite at 650 °C in the presence of carbohydrates.. Slight difference of diverse carbohydrates influence on hematite reduction • New ways of beneficiation of oxidized iron ores
Studies to evaluate the beneficiation of low-grade hematite-magnetite ore (18.64% Fe) have been carried out in China (Liu et al., 2014). Bioprocessing has been considered as an option in the
Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore. It responds best to what is known as gravity separation as well and several types of gravity equipment can be used to refine it, including jiggers, centrifugal separators, and shaking tables.

Among them, magnetite-hematite is a common mixed ore, and its beneficiation usually adopts a combined process flow composed of multiple beneficiation methods. Single Magnetite-Hematite The single magnet-hematite is mostly fine-grained; the gangue mineral is mainly quartz, and some of it contains iron silicate.

Beneficiation of Magnetite–Hematite Ores. Studies have found that the ore contains both strongly magnetic and weakly magnetic iron minerals. To enrich the strongly magnetic component of the samples (magnetite), the field induction in the mineral separation zone must be in the range of 0.1–0.2 T.
Magnetite concentrate grades are generally in excess of 70% iron by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price. Hematite. Due to the high density of hematite relative to associated silicate gangue, hematite beneficiation usually involves a combination of beneficiation techniques.
Hematite and goethite are very friable during mining and processing due to inter-granular pore spaces and voids along the weaker bedding planes. These friable particles break down and account for the iron content of the slime. Ore samples, having magnetite and martite do not participate in the formation of the slime as they are very massive .

Polymetallic magnetite – hematite (siderite) iron oreThe iron minerals in this type of ore are mainly magnetite and hematite or siderite, medium to fine grain inlay; gangue minerals are silicate and carbonate minerals or fluorite; Pyrite, chalcopyrite and rare earth minerals.The ore dressing method of such ore is the most complicated in iron ore.
Magnetite ores require varying degrees of processing and beneficiation to produce an iron ore suitable for steelmaking purposes, ultimately contributing to higher production costs. Magnetite concentrates typically range between 65 to 70% Fe and are increasingly being sought as a preferred feedstock for steelmaking, particularly those concentrates with low impurities.
Iron ore Processing Plant. At present, there are about 300 kinds of iron-bearing minerals found in nature. According to the classification of chemical composition, the common iron ore mainly includes magnetite, hematite, limonite and siderite. Different properties of iron ore, its processing technology is naturally different.
PJSC ArcelorMittal Kryvyi Rih, Mining department, 2013, Beneficiation process of magnetite quartzite on ore beneficiation plant, technological instruction (internal report, in Russian).
The majority of steel production is supported by iron ore sourced from high-grade hematite deposits, although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix.
