Magnetic separation, dry or wet, was ineffective for removal of ferromagnetic particles from printed circuit board PCB dust. By using octyl phenol ethoxylate OPE up to 60 ppm in 10 gl pulp of 150212 m PCB dust, 92 iron and 85 nickel recoveries were obtained under wet lowintensity 1370 Gauss magnetic separation.

Steel is already magnetic on an atomic level, but when the atoms are arranged at random, their magnetic effect is canceled out on a macroscopic level. All of these methods allow the atomscale magnets to align with another magnetic field, causing them to all exert a magnetic force in the same direction.

An electromagnetic wheel is used in the magnetic separation process of ore from gangue as it seperates the magnetic particles from the nonmagnetic particles. The magnetic particles get attracted to the magnetic wheel and thus get seperated from the gangue. iii In the froth floatation process, the ore floats on the top the gangue settles

The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite Fe 2 O 3, magnetite Fe 3 O 4, siderite FeCO 3, and iron pyrites FeS 2 can be separated by the process of magnetic separation.

This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite FeCrO 2 2 being magnetic can be separated from the nonmagnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
