The effective utilization and clean recycling of tailings are important to solve land occupation and waste mine pollution problems. A semi-industry experiment of hydrogen-based mineral phase transformation for tailings is conducted with a roasting temperature of 500 °C, a reducing gas concentration of 20 %, a total gas volume of 12 m 3 /h, and a handing capacity of …
Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry.
As shown in Table 1, Fe was the main recovery component with a content of 24.27%, and SiO 2 was the main impurity with a content of 60.39%. The analysis of Fig. 1 shows that hematite and magnetite are the main iron-bearing mineral in raw ore. Gangue mineral was mainly quartz. The dissociation degree and intergrowth relationship between hematite, …

rough hematite concentrate with Fe total content of 54.5% and hematite recovery of 73.6%. Further concentration using shaking table increased quality of hematite concentrate to 62.2% of Fe total. Separation of spirals middlings did not result in acceptable indicators. Mineralogical investigation showed that about 20% of hematite in the middlings is
In iron ore processing plants, different tailing streams are usually transferred to the tailings thickener for partial dewatering and finally transferred to the tailings dam as a single stream. Therefore, the mixing of different tailings streams happens. This way can challenge the process of reprocessing the tailings in the tailings dam since the mixing of different tailings …
As shown in Fig. 5, the Fe grades of both the concentrate and tailings decreased with the increasing magnetic field. The yield of tailings also experienced a downward trend as the magnetic field increased, while the concentrate yield increased. The Fe phases of the concentrates were summarized in Table 5. Fe was mainly present as hematite (94. ...
The recovery and grade of the obtained SiO 2 were analyzed to evaluate the performance of the S-HGMS technology for the separation and extraction of quartz from HTs. The SiO 2 recovery and grade were calculated using the following equations: (1) Recovery = m 1 × C 1 m 2 × C 2 × 100 % (2) Yield = m 1 m 2 × 100 % where m 1 and C 1 denote the mass of the …
The separation technology provides for production of iron ore concentrate with total iron content of 65.9% and recovers 91.0% of magnetite and 80.5% of hematite from the tailings containing 20.4% ...
Hematite is an incredibly protective, grounding stone. With gentle energy, it shields against negativity, absorbing and deflecting bad vibrations and harm from the environment, including geopathic stress, electromagnetic smog and thought-forms. Hematite helps to strengthen physical energy and stamina, making it especia
Under suitable operating conditions, a concentrate assaying 56.45% Fe with 70.10% iron recovery was finally produced from a hematite-quartz mixture assaying 30.60% Fe, at a high mass weight reaching 38.00%.
