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., 2000).As discussed in Chapter 10, 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.
Wet drum magnetic separators of special design may be used as a magnetic thickener for thickening purpose of magnetic concentrates, usually at the end of a magnetic separation process, or as a high-intensity magnetic separator, for the removal of very fine ferromagnetic particles and iron corrosions produced in the grinding process of a ...
Dec 02, 2003· The magnetic separation was investigated for Co 2+ (9500 × 10-6 cm 3 mol-1) andFe3+ (14600 × 10-6 cm 3 mol-1) ions and for Cr 3+ (6200 × 10-6 cm 3 mol-1) and Al 3+ (−2 × 10-6 cm 3 mol-1) ions.The metal ion solutions were spotted on a silica gel support, and exposed to a magnetic field of 410 kOe 2 cm-1 intensity × gradient. The Co 2+ ions move farther toward the maximum field than the ...

Jun 20, 2018· The scope of this work is to develop and optimize a reductive roasting process followed by wetmagnetic separationfor iron recovery from bauxite residue (BR). The aim of the roasting process is the transformation of the nonmagnetic iron phases found in BR (namely hematite and goethite), tomagneticones such as magnetite, wüstite, and metallic iron.
Magnetic separationis a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in amagneticfield, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) bymagneticfields are known as “Ferromagnetics”, those lesser (though noticeably) affected are known as ...
