Modern high-gradient magnetic separation (HGMS) initially originated from a magnetic filter patented in 1937 by Frantz [1], in which the ferromagnetic matrix of fine wires or rods was first introduced into a uniform magnetic field to increase the magnetic field gradient by several orders of magnitude [2].The steep increase in …

As shown in the figure, an electron of mass m, charge e, and negligible speed enters the region between two plates of potential difference V, and plate separation d, initially headed directly toward the higher-potential top plate in the figure. A uniform magnetic field is directed perpendicular to the plane of the figure.

Magnetic separation has been proposed to greenly separate chalcopyrite and talc several decades ago, due to their extremely similar floatability of minerals. However, this approach was not achieved initially due to the inadequately magnetic induction of traditional magnetic separation, and fine particle size of chalcopyrite.

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.

Magnetized Roasting. It is a physical and chemical reaction process that turned weakly magnetic minerals (such as hematite, limonite, siderite, and pyrite) into strongly magnetic minerals (such as magnetite, γ Fe 2 O 3, and pyrrhotite).

Figure 11.7 A negatively charged particle moves in the plane of the paper in a region where the magnetic field is perpendicular to the paper (represented by the small × × 's—like the tails of arrows). The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.
