Jul 25 2019 Another common method of iron ore concentration magnetic separation uses magnets to shift and concentrate magnetic particles like iron most commonly through a drum or cross belt separator The processed ore is then graded into fines and lumps. View Details Send Enquiry.

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

Concentration of ore is the process used to extract useful minerals by separating the gangue particles. Concentration of ore can be done by 4 methods: Hydraulic Washing, Magnetic Separation, Froth Floatation, Leaching. Hydraulic washing depends upon the weights of the metal and gangue particles. Magnetic separation depends on the magnetic ...

Magnetic separation Method By this method, those ores can be concentrated which either contain impurities which are magnetic or are themselves magnetic in nature. For example, the tin ore, tinstone (SnO 2 ) itself is non-magnetic but contains magnetic impurities such as iron tungstate (FeWO 4 ) and manganese tungstate (MnWO 4 ).

3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.
