The iron grade was 26.55%. The X-ray diffraction (XRD) analysis and chemical composition of the sample are shown in Fig. 1 and Table 1, respectively. The primary minerals in the iron ore were hematite, siderite, and quartz. Due to the fine particle size of the mineral particles in this ore sample, laser particle size analysis was conducted.Traditionally, the settling and thickening of tailings rely on gravity settling in the vertical sand silo. A number of advanced technologies are used to increase the extraction rate of minerals by grinding the crushed ore into increasingly fine particles . More than 80% of tailings particles have size less than 74 μm in some mines.An experimental study on the flocculating settling of PLOS

Application of Enhanced Gravity Separators for Fine Particle
Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity A laboratory scale selective flocculation process capable of recovering iron oxide from a sample of ultrafine (less than 10 μm) iron ore tailings containing kaolinite as the main gangue mineral has been developed. Experiments were carried out (i) to select the most appropriate flocculant from a large range of commercially available starchesOptimisation of selective flocculation of ultrafine iron ore

Assessment of a selectivity criterion for upgrading ultrafine iron
Traditionally, the choice amongst different upgrading techniques or in finding the optimum operating conditions for a given upgrading technology depends on whether one is looking at the grade or the recovery of the valuable mineral in the concentrate. In fact, the conclusions are not usually the same. This is because the best The depletion of rich and high quality iron ore reserves in recent years has necessitated the exploration and utilization of low grade iron ores (Li et al., 2020a, Li et al., 2020b, Li et al., 2020c, Liu et al., 2020, Yuan et al., 2020).
