The tailing surface was covered by many micron-sized flaky particles with the typical elements of Fe, Mn, and V (Fig. 2 a). The XRD patterns also indicate that Fe, Mn, and V oxides are present in the tailings (Fig. 2 b). Berthierine, kaolinite, augite, V 2 O 5, MgO, and Fe 3 O 4 are the main minerals in the

Fig. 7 b and e are polarized microscope images of garnet and augite in tungsten tailings, respectively, they were all wrapped in N-A-S-H gel and only a part of them participated in the geopolymerization process. The total extinction image in Fig. 7 f proved that the particles in Fig. 7 e were augite. As seen in the PLM images, a small part of ...
The present study investigates the possibility to recover the leftover valuable metals from polymetallic tailings rejected from rougher flotation at Eagle Mines in the U.S. According to the available technical report, the concentration of Ni and Cu in the Eagle mine tailing is estimated to be around 0.7 % and 0.9 %, respectively (Clow, 2017 ...
The Cu flotation tailing was treated with sulfate acid, followed by SNBX of 320 g·t − 1 and terpenic oil of 40 g·t − 1. The S flotation was completed with one roughing–two concentrating–two scavenging flowsheet. The whole flowsheet was shown in Fig. 12. The closed-circuit process result was displayed in Table 3.
In this paper, we focus on low-grade ore and flotation tailings (i.e. tailing inclusive of tailings from operating plants as well as historic storage facilities) from the Bushveld Igneous Complex (South Africa) to review the latest developments in PGE mining waste valorisation.
In order to solve the problem of poor dewatering and high dosage of flocculation in flota-tion tailing sedimentation of bauxite in Henan, composite flocculation of TLT8626, PAM and AS3318 was used for tailing sedimentation experiment, and the effects of compound component and proportion were investigated .The results showed that the clear supernatant fluid could be …

There are four unique flotation technologies—ion flotation (Figure 3a), solvent sublation (Figure 3b), electroflotation (Figure 3c), and absorbing colloid flotation (Figure 3d)—recently developed for recovering REEs from …
Major increases in cost and availability of water is leading to mine operators starting to examine dry tailing solutions more closely. Potential water recovery potentials for copper flotation tailings are shown in the below table. In Chile, current estimates for the cost of desalinated water pumped to the mine are as high as $5 per cubic meter ...
Abstract. Glass-ceramics in the CaO-MgO-Al 2 O 3-SiO 2 system were prepared using Baiyunebo tailing and fly ash as the main raw materials. The effects of iron oxide (Fe 2 O 3) on the crystallization kinetics of augite-based glass-ceramics were studied by using differential thermal analysis (DTA), X-ray powder diffraction (XRD), electron backscatter diffraction …
Flotation tests on pure samples illustrated that PGA has beneficial effects on magnetite depression (with negligible effect on quartz floatability) through reverse flotation separation.

The invention provides a bauxite flotation tailing settlement separation method, which relates to a method for tailing piling of alumina production by floatation mineral processing Bayer method and the modification of front tailings. The method of the invention is characterized in that the modification is carried out by adding lime into the bauxite flotation tailing, so as to lead the …
For full utilization of combustibles, the common practice of flotation operation is to give a relatively low ash concentrate while leaving a medium ash tailing as an inferior fuel. In this case, the dilute flotation tailing is thickened and dewatered, giving a filtering cake containing about 20-30% moisture as the final product.
Rare earth minerals (REMs) contain rare earth elements (REEs) that are important in modern technologies due to their unique magnetic, phosphorescent, and catalytic properties. However, REMs are not only non-renewable resources but also non-uniformly distributed on the Earth's crust, so the processing of REE-bearing secondary resources via recycling is one …
