The results indicated that the iron phase in the raw ore was predominantly metallic iron with an iron particle size below 30 μm, and the phosphorus compound was apatite. By applying MFS to siderite reductive ore containing 37.14% Fe and 0.52 P, a concentrate assaying 66.37% Fe and 0.19 P with 74.32% recovery was produced.
Effect of feed size fraction on the concentrate assay and metal recovery using high intensity magnetic separator. The size labels are: 1 for - 500+20 μm, 2 for - 350+20 μm, and 3 for - 150+20 μm
Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation …

CTG-1030 dry drum magnetic separator: 0.45 T <3 mm: Iron ore in Inner Mongolia (China) The magnetic iron content of the raw ore is 3%, and the grade of the concentrate after sorting is 11.4%. YCG dry permanent magnetic roll: 1.4 T: 75–6 mm: Nanjing Meishan iron ore (China)
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 …
Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of …
In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron …
Chemical phase analysis was used to determine the distribution of iron and manganese elements in the ore, and the results are shown in Tables 2 and 3. Table 2 shows that the iron element is mainly distributed in hematite; the distribution rate of iron is as high as 98.18%, and the contents of magnetic iron, iron sulfide, and iron carbonate …
In the past, a lot of experimental research work on this type of iron ore beneficiation, including reduction roasting – weak magnetic separation process of the selection index is relatively good, but because of its technical difficulties is the need for ultra-fine grinding, and the current conventional beneficiation equipment and chemicals ...
Magnetic separation of magnetic pulse treated and untreated magnetite ore indicates that iron recovery increases from 81.3% in the untreated sample to 87.7% in the magnetic pulse treated sample ...
Magnetic separation of microwave treated and untreated iron ore indicated that iron recovery increased from 39.54% in the untreated sample to 97.95% in the microwave-treated sample.
A mathematical model of the separation in magnetic fluid is described. The complex of separators KC3-1 was developed. Industrial-scale testing results are shown. Gold recovery at all stages of ...
Currently, the most used iron ore beneficiation techniques are gravity, magnetic separation, screening, crushing, and spiral concentration, as outlined in Fig. 2.
ABSTRACT. Comprehensive utilization of tailings resources not only solves environmental problems but also creates huge economic benefits. In this paper, fine weakly magnetic particles were extracted from iron ore beneficiation tailings and silica (SiO 2) was separated and purified using a superconducting high gradient magnetic …
The study of beneficiation indicators of the magnetic separator was carried out using iron ore of the Bapy deposit, which is mono-mineral magnetite. For the study, mixtures of the minus 0.1 mm class were selected with the iron content α = 50% and α = 40%. ... which allows to obtain: gravity gold-containing concentrate with a mass fraction of ...

Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources. For instance, about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China. Iron ore tailings can be recycled as functional materials because these tailings are …
The process of deep reduction and magnetic separation was proposed to enrich nickel and iron from laterite nickel ores. Results show that nickel–iron concentrates with nickel grade of 6.96%, nickel recovery of 94.06%, iron grade of 34.74%, and iron recovery of 80.44% could be obtained after magnetic separation under the conditions …
The quality and quantity of Australia's secondary deposits, which include tailings streams and tailings dams, are higher than most countries' primary deposits. In addition, these secondary deposits have already been mined and processed, meaning that the recovery of high-grade product requires low capital and operating costs.The most widely used …
