The results show that by only adopting traditional magnetization roasting–magnetic separation, an iron ore concentrate containing 57.49% Fe and 1.4% P2O5 at an iron recovery rate of 87.5% and a ...
For instance, pre-melting processes of automobiles consist of (i) shredding, (ii) magnetic separation to remove ferrous scrap components (e.g., Fe and steel), (iii) air separation to remove lightweight materials (e.g., plastic, rubber, and ), (iv) sink-float separation to remove impurities lighter and heavier than Al, (v) eddy current ...
Carbothermic reduction roasting followed by magnetic separation (or acid leaching) processes have been regarded as effective routes to realize the separation of Mn and Fe via enlarging the magnetic property and solubility differences among Mn, Fe and gangue constituents. During these processes, the carbothermic reduction roasting is …
Magnetic separation in molecular biology uses superparamagnetic beads and a magnetic field to provide a simple and reliable method of purifying various types of biomolecule. With an appropriate bead surface coating …
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers
This chapter is focused on reviewing the magnetic separation of particulate matter in fluid phase, especially aqueous solutions, primarily analytical-scale and …
Abstract: Conventional magnetic separation devices are widely used for the removal of tramp iron from a variety of feed materials and for the beneficiation of ferrous ores. These devices for separation of strongly magnetic materials employ a variety of mechanical designs. Recently developed high gradient magnetic separation devices extend the …
Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those …
The need for excellent, affordable, rapid, reusable and biocompatible protein purification techniques is justified based on the roles of proteins as key biomacromolecules. Magnetic nanomaterials nowadays have become the subject of discussion in proteomics, drug delivery, and gene sensing due to their various abilities including rapid separation, …

In this study, a combination of physical and chemical separation processes was used to recover the metallic components of red mud. At first, the impact of carbothermal reduction on magnetic separation of iron was studied. Low magnetic properties of iron minerals resulted in insignificant separation of iron from other …

Metal–organic frameworks (MOFs) are promising nanomaterials with unprecedented capacity to store small molecules. Despite this huge capacity, proposed methods for releasing these molecules are not yet feasible at a meaningful scale, largely because of the strong binding of the molecules and the thermally insulating nature of the …
The coal-based direct reduction–wet magnetic separation process has been used to upgrade oolitic hematite ore in recent years [19–26]. In a study by Kokal et al., HPOHO (49.50% Fe and 0.75% P) was roasted at 900 C for 20 min and the crude concentrate was leached after magnetic separation in 3% dilute sulfuric acid for 1 h. …
Magnetic separation is applied to separate magnetic materials (such as iron, nickel and their alloys) from the non-magnetic material. Electrostatic separation aims to separate conductive material from non-conductive, roughly metal from non-metal. ... Hydrometallurgical routes are commonly more complex and require a higher number of …
Magnetic nanoparticles are highly recyclable, non-toxic, reusable and possess magnetic characteristics that offer advantages of convenient separation upon using an external magnetic field (Lisjak and Mertelj 2018). Magnetic nanoparticles have been also known to have vast potential as catalyst supports.
Magnetic separation is a process that uses magnets to separate magnetic materials from non-magnetic ones in a mixture. This technique takes advantage of the varying magnetic properties of different substances.
