  • Rapid and selective magnetic separation of uranium in

    One-pot magnetic separation of uranium (U) in seawater and groundwater samples has been made possible by synthesizing phosphoramidate functionalized Ag coated citrate-Fe 3 O 4 nanoparticles (NPs). The magnetic saturation value of these functionalized NPs is 27.1 emu g −1.The synergistic extraction mechanism of U(VI) ion by the surface-modified phosphoramidate and citrate molecules make these

  • Separation

    Jan 01, 1997Magnetic separation is specifically used on heavy metals, radionuclides, and magnetic radioactive particles, such as uranium and plutonium compounds. Physical separation often precedes chemical extraction treatment based on the assumption that most of the contamination is tied to the finer soil fraction, which alone may need to be treated.

  • Environmental Code of Practice for metal mines: chapter 2

    Flotation Separation: Flotation is used for the separation of a wide variety of minerals on the basis of differences in surface properties of minerals in contact with air and water. It is the dominant process for the recovery of base metal ores and is also used in uranium and gold processing operations.

  • Ultrahigh uranium uptake by magnetic magnesium ferrite

    Magnetic adsorbents in combination with magnetic separation techniques have received considerable attention in recent years due to their magnetically responsive nature for selective manipulation and rapid separation. Herein, we report a novel kind of magnetic hydrothermal carbon nanosheets loaded with magnesium ferrite as an efficient adsorbent for uranium uptake, in which the original

  • Magnetic and Gravity Methods in Mineral Exploration: the

    Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.
