Isicelo:Olu ngcelele lweemveliso lunommandla wemagnethi okwimvelaphi ephezulu kakhulu ongenakufikelelwa ngezixhobo eziqhelekileyo ze-electromagnetic, kwaye unokwahlula ngokufanelekileyo izinto ezinobuthathaka ezinozibuthe kwiiminerali ezicolekileyo. Ilungele ukuxhamla kwisinyithi esinqabileyo, iintsimbi ezingezizo i-ferrous kunye nezingeyo-ferrous ores metallic, ezifana cobalt ore ukutyetyiswa, ukususwa ukungcola kunye nokucocwa kaolin kunye feldspar non-metal ores, kwaye ingasetyenziselwa ukucocwa ilindle kunye nokucocwa kwamanzi olwandle kunye nezinye iinkalo.
