    attracted by a magnetic field, then such separations are carried out (e.g., in case of iron ores). the ground ore is carried on a conveyer belt which passes over a magnetic roller (fig.6.1). this method has been in use for removing gangue from sulphide ores. in this process, a suspension of the powdered ore is made with water. to it,,what is electrostatic separation? (with pictures),an industrial process used to separate large amounts of material particles, electrostatic separating is most often used in the process of sorting mineral ore. this process can help remove valuable material from ore, or it can help remove foreign material to purify a substance.



    magnetic separation employs the difference in magnetic properties of minerals to effect separation between them. the magnetic separation may be for removing ore particles which are magnetic or conversely to remove magnetic impurities from a product which is non-magnetic. examples are magnetite from quartz or magnetite and wolframite from,a discussion of magnetic separation techniques for,a discussion of magnetic separation techniques for concentrating ilmenite and chromite ores m. dobbins*, j. domenico*, and p. dunn* *outotec (usa) inc.—minerals processing, physical separation magnetic separation has long been used to upgrade and beneficiate a wide variety of industrial minerals.
