The use of the "magnetic seeding (magnetic fishing)" technique [21, 42,49,55] allows to significantly expand the spectrum of nanoparticles that can be separated from the water by a magnetic field ...
For instance, magnetic seeding flocculation was employed to remove arsenic by applying magnetite (Fe 3 O 4) and polymeric ferric sulfate (PFS), with these two substances being separated using open or high gradient superconducting magnetic separation (OGMS or HGMS), giving rise to increase of arsenic removal from 72.5% to …

Selective flocculation of fine iron minerals to accommodate HIMS process is an effective approach. According to the different mechanisms of agglomeration, it can be divided into hydrophobic flocculation, magnetic agglomeration (magnetic seeding agglomeration), and polymer-bridging flocculation [[10], [11], [12], [13]].
Particle separation by a one-step or "batch" magnetic seeding operation is investigated using a population balance modeling approach. This modeling technique accounts for the concurrent orthokinetic coagulation between magnetic seed particles, the orthokinetic coagulation between magnetic seed particles and target particles, and the …

Agglomeration of magnetic nanoparticles. The formation of agglomerates by salt-induced double layer compression of magnetic nanoparticles in the absence and presence of an external magnetic field was investigated experimentally as well as computationally in this study. The structures of the agglomerates were analyzed through …
The migration process of magnetic nanoparticles and colloids in solution under the influence of magnetic field gradients, which is also known as magnetophoresis, is an essential step in the separation technology …
To clarify the role of magnetic seeding on the separation of ferrihydrite by HGMS, a part of experiments were done without magnetite addition at different pH values (Fig. 2).Since ferrihydrite without the addition of magnetite particles cannot be separated magnetically, magnetic seeding technique was found to be essential for the separation …
Particle aggregation by magnetic seeding was proposed for removing the coal-fired PM 10.To better understand the particle aggregation properties by magnetic seeding, experiments on the fly ash particles in the size range of 0.023–9.314 μm were conducted in a uniform magnetic field by seeding magnetic particles of Fe 3 O 4 and γ …
In magnetic seeded filtration, a hetero-agglomeration between non-magnetic target and magnetic seed particles is induced and the agglomerates are subsequently removed by magnetic separation.
This paper proposed a novel process, magnetic seeding and separation, to promote the growth and aggregation of goethite precipitate on the surface of the magnetic seeds, forming a core-shell structure. ... which could easily dominate the other potentials and result in agglomeration in the primary minimum (Stolarski et al., 2007, Yiacoumi et …
Temperature-Switchable Agglomeration of Magnetic Particles Designed for Continuous Separation Processes in Biotechnology ACS Appl Mater Interfaces. 2015 Jul 8;7(26) :14279-87. ... Additionally, enhanced magnetic separation was observed for the modified particles. Ionic monomers were integrated into the polymer chain to …
Magnetic separation can recover nonmagnetic and diamagnetic minerals, which expands the separation limit of magnetic separation. In theory, any mineral can be recovered by magnetic separation with this technology, and the lower limit of the processed particle size is much lower than the particle size achieved by other magnetic …
In magnetic seeded filtration, a hetero-agglomeration between non-magnetic target and magnetic seed particles is induced and the agglomerates are subsequently removed by magnetic separation. The necessary addition of magnetic material constitutes the main criticism of the process.
Seeding of ferrihydrite with magnetite To clarify the role of magnetic seeding on the separation of ferrihydrite by HGMS, a part of experiments were done without magnetite addition at different pH values (Fig. 2). Since ferrihydrite without the addition of magnetite particles cannot be separated magneti- cally, magnetic seeding technique was ...
The removal of iron ion from leaching solution is critical for the recovery of value metals, with the method of choice commonly being crystallization (precipitation). This paper summarized the new improvements in iron removal by precipitation methods in recent years and proposed a novel process, magnetic seeding and separation. The new …
It can also be extended to the removal of non-magnetic particles by using magnetic seeding (Chin et al. 2006;Bakhteeva et al. 2019aBakhteeva et al., 2021a, and by combination with coagulants to ...
Remaining concentrations (given in percent of starting concentrations, equal to approximately 1 mg/l for each ion) of heavy metal ions after precipitation and magnetic separation are shown in Fig. 4 a for three water cleaning cycles with the same magnetic particles. With the exception of Hg, more than 95% (often more than 99%) of the heavy ...
A positive aspect of agglomeration, however, is that it leads to improved separation in the magnetic separation process [33, 41 – 44]. In order to be able to make statements about the agglomeration behaviour of oligo(dT) 25 -functionalized and mRNA-loaded magnetic particles, particle size distributions were determined.
