Report issued by the Bureau of Mines over studies conducted on the removal of magnetic materials from iron ores. As stated in the introduction, "this report discusses briefly operations and trends in magnetic separation, explains magnetic separation, describes and classifies the machines used, and outlines their development" (p. 1). This report includes tables, and illustrations. Abstract: Magnetic particles have been being adopted in various areas, ranging from engineering to biomedical fields such as magnetorheological fluids, separation of magnetically tagged DNA, drug delivery and identification of biological species. The particles in a fluid domain can be controlled by an external magnetic field. The magnetized particles also interact between themselves, .
A new permanent magnetic separator was introduced to treat the ores with the characteristics of weak magnetic iron minerals and in a fine size range. The new machine was applied to the iron removal from potash feldspar. The effects of the magnetic field intensity, pulp density and grinding fineness on the iron removal were investigated. The optimized operation parameters were . This work is devoted to the experimental study of the magnetic separation of medium sized nanoparticles ( nm) which are separated from the suspending fluid .
Sequestrating anionic and cationic dyes from wastewater using spray dried biopolymeric magnetic composite: Experimental and theoretical studies Article in Journal of Hazardous Materials The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation. Thermodynamic calculations using HSC Chemistry 61 were utilised to determine the equilibrium compositions of the reaction products as a .

Ing. Pier Luigi Ribani Esame ﬁnale anno Based on the theories constructed in this paper, systematic investigations of elliptic matrix in transversal HGMS will be conducted in follow-up studies, including its separation performance for actual weakly magnetic by: Theoretical and experimental study on elliptic matrices in the transversal high gradient magnetic separation Article in Minerals Engineering September with 91 Reads.
This paper investigates the mechanisms of a new technique, Vortex Magnetic Separation (VMS) which can not only greatly reduce the serious mechanical entrainment problem in HGMS, as normally applied at low Reynolds Number Re (= 2 ϱV o a / η where ϱ is the density of the fluid, V o is the velocity of the fluid, a is the radius of the wire and η is the viscosity of the fluid), but also Cited by: 8.
R.R. Oder, in Studies in Surface Science and Catalysis, 1. Abstract. This paper presents preliminary results using the Magnetic Micro-Particle Separator, (MM-PS, patent pending) which was conceived for high throughput isothermal and isobaric separation of nanometer (nm) sized iron catalyst particles from Fischer-Tropsch wax at o C.
In recent years, magnetic separation has attracted considerable attention as a technique for the separation of paramagnetic particles from the media carrying them.
Equipment may be at least approximately specified by theoretical formulae, or by analysis of the results of laboratory experiments. study was to perform magnetic separation of minerals from rock samples in order to enable the identification of the minerals by XRD.
For this phases possible, which proves that magnetic separation by Frantz is a method which can assist analyses by. XRD. Acessed June To adopt the theoretical models for studying effect of influencing parameters, validity of the models is substantially important.

Watson, Zhengnan Li, Theoretical and single-wire studies of vortex magnetic separation, Minerals Engineering, /(92) 3 hours ago Previous theoretical studies have pointed to the existence of all kinds of many-body physics in the surface states of rhombohedral graphite—including high-temperature magnetic.
Carrier magnetic separation has been proposed for more effective separation of water and solids from acid mine water to generate very pure water (Feng et al., ).As discussed in Chap dissolved heavy metals like zinc and copper can be recovered from acid mine drainage (AMD) by selective precipitation controlling the pH for the precipitation of specific metals.

Department of Chemical Engineering, Virginia Polytechnic Institute and State University, Blacksburg, VA Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose.
For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.

This book is based on the contributions to a course, entitled Applied Magnetism, which was the 25th Course of the International School of Materials Science and Technology.
The Course was held as a NATO Advanced Study Institute at the Ettore Majorana Centre in Erice, Sicily, Italy between the 1st and 12th Julyand attracted almost While a number of studies in literature report the use of various mFFF approaches, these primarily focus on the use of mFFF for characterizing small volumes of micro- or nano-particles or for the separation of magnetic particles from non-magnetic materials [24,25,26].
Very little attention has been given to mFFF as a size-specific separation. Magnetic cell labeling. Fundamental to any magnetic cell separation approach are the magnetic forces that are applied to the targeted cells.
This magnetic force is typically the result of an externally applied magnetic field interacting with magnetic nano or microparticles bound to the targeted cell, typically through an antibody-antigen interaction.Theoretical and experimental results for the single wire studies in high gradient magnetic separation are presented.
The particle trajectory model is used for determining the qualitative effect of the various operating parameters, for determining the capture cross section and for determining particle trajectories.
