High-gradient magnetic separation (HGMS) for magnetic materials beneficiation like kaolin clay, steel and power plants
High-gradient magnetic separation (HGMS) is used to sep-arate magnetic materials from a nonmagnetic liquid medium. This process has traditionally been applied in kaolin clay beneficiation, the removal of iron particles from process streams in steel and power plants, and wastewater treatment of bacteria and solids through magnetic seeding.
Benefits of Magnetic Separation
HGMS can be used to separate very fine particles of radioactive material from solid, liquid, or gas waste streams, magnetic particles trapped in steel wool or nickel foam. It reduces the volume of waste to be treated and thus reduces the volume of acids needed for treatment processes as well.
We have shown that HGMS can be used to concentrate plutonium and uranium in waste streams and contaminated soils. One of the major benefits of this technology is that it only partitions the existing waste volume. It does not create additional waste. The ability to concentrate the actinides from extraneous materials before further processing reduces the volume of waste to be processed and yields more efficient recovery or treatment operations. For example, it reduces the volume of chemical reagents (acids) necessary for subsequent operations, it allows a more efficient ion excbmge or solvent extraction, and it reduces the chemicals in subsequent waste treatment operations.
Application Of High Gradient Magnetic Separator:
High gradient magnetic separator in our country is mainly of electromagnetic type. And it has many advantages, like high concentration ratio and recovery ratio, wide range of the sorting size, the magnetic medium is difficult to jam, easy operation and maintenances, etc. This machine can sort the weak magnetic minerals, medium magnetic minerals and strong magnetic minerals and remove impurities and purify the non-metallic minerals. For example:
- Ferrous metal mining: martite, hematite, limonite and siderite and chromite and manganese ore recovery, etc.
- Non-ferrous metal mining: separated for wolframite, garnet.
- Rare metals minerals: recycle of Zinnwaldite, monazite, and xenotime.
- Non-metallic minerals: purity of quartz, feldspar, kaolin, refractory materials.
- Other aspects: wastewater treatment in steel works and power plant, cleaning the raw chemical material contaminated by catalyzer.

High-Gradient Magnetic Separation (HGMS) Plays an Important Role in Radioactive Waste Remediation
Decontamination of materials such as soils or wastewater that contain radioactive isotopes, heavy metals, or hazardous components is a subject of great interest as indicated by the growth of waste remediation and minimization efforts. Conventional treatments of these wastes include both chemical and physical methods. Magnetic separation is a physical separation process that segregates materials on the basis of their magnetic susceptibility. Magnetic separation of radioactive wastes has been shown to reduce the volume of these wastes as well as to reduce the chemical reagents necessary for further remediation.
The HGMS method can be used to separate magnetic components from solids, liquids, or gases. A diagram of the method is shown in Figure 1. Usually, contaminated material is slurried with water and passed through a magnetized volume. Field gradients are produced in the magnetized volume by a ferromagnetic matrix material such as steel wool or nickel foam. Ferromagnetic and paramagnetic particles are extracted from the slurry by the ferromagnetic matrix. The diamagnetic fraction and fluid pass through the magnetized volume. The extracted particulates are then flushed from the matrix when the magnetic field is turned off.
In many situations radioactive contaminants are found concentrated in the fine-particle-size fraction of less tbm 20 microns. For effective decontamination of the fine-particle-size range most conventional operations resort to expensive chemical dissolution methods for treatment. HGMS is able to separate out particles in the range of 90 to ~0.1 microns effectively without chemicals. (The technology is currently used on a commercial scale in the kaolin clay industry.)
