Magnetic Separation of Sulphide Minerals: Techniques
Traditionally magnetic separation is associated with iron bearing materials/ specifically magnetite, as magnetite ore for a long time has been recovered by low intensity permanent magnet separators. In the sixties, high intensity and high gradient magnetic separators were developed mainly for processing hematite.

Copper Mineral | Uses and Properties
Uses of Copper. Native copper was probably one of the early metals worked by ancient people. Nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores.

Intensity Magnetic Separator
As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at a distance of 50 mm from …

HIGH INTENSITY DRY ROLL MAGNETIC SEPARATOR DHIMS
The magnetic roll is configured as a head pulley in the separator. A thin belt, usually 3 to 20 mils in thickness, runs around this magnetic head pulley and conveys feed material to the magnetic field. When feed enters the magnetic field, the non-magnetic particles are discharged from the roll in their natural trajectory.
