Which of the following ores cannot be concentrated

Magnetic separation based on differences in magnetic properties of the ore components. If either the ore or the gangue is attracted towards the magnetic field, then the separation is carried out by this method. For example, iron ores are attracted towards the magnet, hence, non–magnetic impurities can be separated from them using magnetic separation.

2021-2-27 · Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as “Ferromagnetics”, those lesser (though noticeably) affected are known as ...
