In the first stage, iron ore is screened into 0-1 mm & 1-2 mm sizes & both of these materials are separately fed to the magnetic separator. The non-mag portion of 1-2 mm is crushed again to 0-1 mm size & re-fed into the magnetic separator. This will help to extract the maximum Fe from the iron ore & to reduce the Fe lost in the non-mag.
