The XRD patterns of magnetic separation concentrate show that the main mineral phases in concentrate are magnetite (Fe 3 O 4) and fluorite (CaF 2 ), which can …
The magnetic separation experiment was repeated by varying the applied magnetic intensity from 0.05 to 1.0 T to confirm the optimal magnetic intensity. Thus, the optimum magnetic separation process design was attempted by establishing the optimum grinding time and magnetic intensity. 3. Results and discussion3.1.
Herein, we introduce a new type of magnetic separation system, the magnetic spinner (mag-spinner), which is a Facile, Affordable, Simple, and porTable (FAST) separation system of target analytes from complex samples (Scheme 1). Mag-spinner adopts a fidget spinner system so that any unwanted residues can be removed …
Between 2000 and 2010, magnetic separation and flotation were introduced to beneficiate the Sichuan rare earth ore. A combined "gravity-magnetic-flotation" process was developed (Li et al., 2002, Xiong and Chen, 2009), leading to significant increases in rare earth oxide (REO) content and recovery from the Maoniuping rare earth concentrate.
The magnetic sorbent was readily separated from fly ash by magnetic separation, leaving the fly ash essentially free of sorbent contamination. In initial in-plant tests, the sorbents were able to capture mercury from the flue gases of an operational, full-scale, coal-fired power plant.
Magnetic cell separation has become a key methodology for the isolation of target cell populations from biological suspensions, covering a wide spectrum of applications from diagnosis and therapy in biomedicine to …
Introduction. As early as 1792, the use of magnetism and magnetic materials in separation applications has been documented [1, 2].Introduction of the magnetic-activated cell separation (MACS) systems, which couple small superparamagnetic particles bound to cells with high gradient magnetic fields (generated using a ~ 0.6 Tesla external …
Bayan Obo ore contains mainly bastnaesite, monazite and associated iron, fluorite, calcite, dolomite, barite, and trace amount of columbite. Due to its complex mineral compositions and similar mineral properties, it is difficult to separate and obtain rare earth and fluorite concentrates with high purity by conventional magnetic separation and …

The mineralogical characteristics of tantalum–niobium ores from Songzi were investigated using mineral liberation analyzer (MLA) and chemical analysis. In particular, the chemical composition, phase composition, particle size, and dissemination characteristics of the ores were studied in detail. Results show that Ta2O5 and Nb2O5 have grades of …
MLA-based partition curves for magnetic separation | Semantic Scholar DOI: 10.1016/J.MINENG.2016.05.015 Corpus ID: 99318094 MLA-based partition curves for …
Mineral Liberation Analyzer (MLA) and dry magnetic separation tests were performed on the resulting products. The MLA test results showed that the gangue in fine-grained iron ores was more difficult to liberate than in coarse-grained iron ores. The dry magnetic separation tests indicated that only 15.23% of gangue could be rejected for …
3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.
The magnetic separation of cells based on certain traits has a wide range of applications in microbiology, immunology, oncology, and hematology. Compared to bulk separation, performing magnetophoresis at micro scale presents advantages such as precise control of the environment, larger magnetic gradients in miniaturized dimensions, operational ...
This book covers the following topics: physical principles of magnetic separation; magnetic separation techniques; theory of high-gradient magnetic separation; practical aspects of magnetic separation; industrial applications of high-gradient magnetic separation (including the magnetic beneficiation of coal and fly ash); and the economics of …

For magnetic separation the MLA data has to be combined with mineral susceptibilities using additional software. This article describes the calculation of partition curves for …
The distributions of oxides in the magnetic separation products are presented in Figure 13. After magnetic separation, a final magnetic product weighing about 27.5% of the feed was concentrated. Fe 2 O 3, MnO, TiO 2, and MgO had significant recovery peaks in the magnetic product at rates of 39.5%, 43.2%, 33.4%, and 33.5%, …
Additional REE-bearing minerals, with a TREO (%) of 45.0%, were recovered as magnetic products in the third magnetic separation process. Therefore, the total yield of REE concentrate was 45.4%, with a …
The mass-independent property of magnetic translation described in equation (1) is an essential factor for achieving separation; that is, when a solid particle is released in an area of common B(x) distribution with a small initial velocity, its position and velocity during translation are uniquely determined by its magnetic susceptibility 1 ...
This study illustrates the applicability of MLA data for the in-depth analysis of a magnetic separation process. Partition curves are easily calculated from MLA data when the magnetic susceptibility of the minerals concerned is known.
