For the reduction products, i.e. low grade magnetite, the best results occurred when the applied magnetic field was 119·4 kA m âˆ’1 and the particle size was âˆ’0·048 mm, with the iron grade of the concentrate being 62·5% and the recovery rate being 91·1%. The produced magnetite can be reoxidised to maghemite at temperatures below 300°C ...

However, low-grade hematite ores cannot be used directly in blast furnaces because of their low iron minerals content, which are associated with quartz and other gangue minerals (Yu et al., 2017). Therefore, low-grade hematite ores must be treated by mineral processing methods (e.g., flotation and magnetic separation) to obtain the iron ...
REEs (La-Lu) are the least soluble trace elements and are relatively immobile during weathering, low-grade metamorphism, and hydrothermal alteration (Rollinson, 1993, p.137).The chondrite normalized REE pattern for the Lambir and the Sibuti sediments shows an enrichment of light REE (LREE) and flat heavy REE (HREE) with a negative Eu anomaly (Fig. 7.5).
The mappable â€˜first-orderâ€™ mineralisation control, however, is the hypogene sulfide type and abundance intimately controlled by hematite alteration intensity. Second-order controls are sharp permeability, rheological competency-contrast and/or redox boundaries, where high-grade mineralisation wraps around their margins.
