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.Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores (DSOs) generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.Low-grade hematite ores require 8 Developments in iron ore comminution and ScienceDirect

Due to the depleting reserves of DSO ores and increasing development of low-grade hematite and magnetite deposits, the need for iron ore comminution and beneficiation is increasing. Even the DSO ores are requiring a higher level of processing as mining operations are extended below the water table where ores are wet and more sticky Washing of iron ore fines and slime (10% and 25% w/v, slurry concentrations) with two types of surface-active agents (sodium humate (synthesized) and AD 200 (commercial)) at varying concentrations at pH 8 was conducted for ascertaining the efficacy of dispersants in beneficiating the low-grade iron ores.

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.Hematite and quartz present in banded iron ore are intimately associated with one another and require fine grinding for the liberation of mineral particles. The influence of the thickness of bands on the liberation and flotation response of banded hematite quartzite (BHQ) ore is investigated.

Table 4-3 shows the estimated energy requirements for a surface iron mine in the U.S. The iron mine operates over a 22-year lifetime with a 110 million-ton output at the end of its life. The mine runs 364 days per year with two 8.00 hour shifts per day, which gives it a daily production rate of 13,699 tons per day.Therefore, simultaneous roasting of siderite and low-grade hematite ores has been proposed as a promising thermal beneficiation process (Yu et al., 2020) that requires no additional fossil fuel reducing agents and could represent a comparatively low carbon footprint process for thermal beneficiation.Thermal beneficiation of refractory iron ore ScienceDirect
