Concentration of Ores Study Material for IIT JEE

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.

Jan 17, 2020 · The stability criterion for the magnetic separation of rare-earth ions is studied, taking dysprosium Dy(iii) ions as an example. Emphasis is placed on quantifying the factors that limit the desired high enrichment. During magnetic separation, a layer enriched in Dy(iii) ions is generated via the surface evaporation of an aqueous solution which is levitated by the Kelvin force.
