beneficiation study of an ultra-fine-grained hematite ore
beneficiation study of an ultra-fine-grained hematite ore

Beneficiation of low-grade fine-grained hematite ores becomes increasingly important due to rapid depletion of high quality iron ore resources. However, fine particles, especially ultra-fine particles, make efficient beneficiation of these ores more difficult. Therefore, methods to reduce the influence of fine particles must be considered to achieve better beneficiation performance

(2) The sand-stained ore can be separated from the coarse-grained ore-free waste rock by washing, and the obtained fine-grained part is de-sludged and selected. (3) The ore needs to be hand-selected or photo-selected, and the slime stains the surface of the ore block, making it difficult to identify

Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are 3.23 and 3.08, respectively, which are consistent with those of metal tailings but much higher than those of natural soils

In this method, the barren overburden is removed, often by draglines or shovels, and high-pressure water jets are used to break up and dislodge the tin-bearing sand. A submerged gravel pump then sucks up the slurry of mud and water and raises it to a series of sluice boxes, or palongs, which slope downward and have baffles placed at intervals along their length
