A discussion of magnetic separation techniques for ...

magnetic separation early in a process can greatly benefit an operation if a low-grade final tailing, or a clean marketable product, can be produced, since it alleviates both drying and dry storage costs. While WHIMS use can be advantageous, a common drawback of conventional designs is entrapment of non-magnetics in the magnetics product, particularly when treating finer particles. This ...

EFFECTIVE PROCESSING OF LOW-GRADE IRON ORE THROUGH

Recovery of valuables from natural ores by gravity concentration process is one of the oldest and most economic techniques (Brut, 1999). Although in the twentieth century gravity concentration has been partially replaced by other techniques, notably, flotation and magnetic separation, they have not made it obsolete. Gravity separation techniques are widely used in mineral beneficiation ...

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. Besides, metal ores can be magnetic as well as electrically ...
