Mechanism of recovery processes for rare earth and iron

Sep 21, 2020 Rare earth (RE) and iron minerals in tailings exhibit fine embedded granularity and are closely associated with silicates, carbonates, and other lode minerals, which are difficult to be recycled. Studies of these tailings led to some new processes of ore dressing, involving grinding, RE flotation, strong magnetic separation, and positive iron flotation. In this closed circuit process, RE and

The research is aimed at study of the probable recovery of iron from the tailings of the Olcon mining company located in the north-western Arctic zone of Russia. Material composition of a sample from a tailings dump was analysed. The authors have developed a separation production technology to recover magnetite-hematite concentrate from the tailings. A processing flowsheet includes magnetic

The XRD study was taken up to identify mineral phases in the chromite tailing sample. The diffractogram is shown in Fig. 2. From this figure, it can be seen that along with chromite, hematite and goethite are the major iron-bearing mineral phases whereas gibbsite, kaolinite and quartz occur as

During the processing of iron ores, a large quantity of low-grade tailings containing abundant iron values in fine particle size range is produced. A novel HGMS-Centrifuge process is proposed to recover iron values from a low-grade hematite tailings. In this process, the tailings is effectively roughed with pulsating high pulsating high gradient magnetic separator to produce a relatively high

Apr 19, 2016 Hematite Flotation Circuit. Each flotation circuit consists of a four cell open flow roughing section followed by a two cell scavenger. The scavenger concentrate is returned by gravity to the third rougher cell and the rougher concentrate from the first rougher cell is sufficiently high grade ( + 58% Fe) to combine with the cleaner concentrate

Feb 03, 2021 The use of a biosurfactant (BS) in mineral flotation offers numerous advantages over conventional surfactants, such as their low toxicity, high degradation kinetics, and potential for selectively treating low-grade ores. In the present study, the use of a biosurfactant obtained from Rhodococcus opacus bacteria for the flotation of hematite from iron ore tailings was evaluated.

Dec 29, 2017 The Fe mineral phase and its distribution is shown in Table 4, the main constitute is hematite-limonite which account for 91% of total Fe. The recoverable Fe in the oolitic iron ore is mainly in the form of magnetite and hematite-limonite, theoretically the Fe recovery (ε) can be 91.23%.

This paper presents the geotechnical properties of the zinc/lead mine tailings from Tara Mines in County Meath, Ireland. The coarser and finer materials from the mechanical crushing and grinding processes were classified as slightly sandy silt and clayey silt, with high specific gravity of solids values of 2.78 and 2.82, and bulk density values of 2.01 and 2.08 tonne/m 3 , respectively.

Most of the hematite was lost in the tailings as fine particles. Another ore sample(B) of 31.5% Fe was prepared from ore sample A by removing magnetite using low intensity magnetic separation at H~800 De. X-ray diffraction analysis showed hematite, augite, quartz, fluorite and carbonates as the main minerals.

The tailings from the re-processing plant will be re-deposited in a new area far from urbanization, allowing for the rehabilitation of the real estate currently occupied by these historic tailings. The first step in the process involves a mild-regrind and mild acid leach of the tailings (pH 2.5 to 3.0) to dissolve up to 40% of the uranium.

Beneficiation of Haematite from Fluorspar Tailings by

flotation of haematite from the tailings has been investigated using a batch, bench –scale mechanical cell. Characterisation of the fluorspar tailings was done and effects of various operating parameters on the recovery of haematite were studied. The results showed that 80% of the tailings particles were - 150 m in size and major

Jul 26, 2010 The chemical composition of a typical tailing sample is also shown in Table 1. Acid digestion of the tailing sample led to removal of the hematite phase and left an acid insoluble residue containing predominantly quartz. The X-ray diffraction pattern for the tailing and the acid insoluble samples are given in Fig. 1(a), which clearly shows the presence of hematite (Fe 2 O 3) and quartz
