The purification of raw iron oxide obtained from iron preCIpItation of the Zinc leachresid ue using the recrystallization method with Naz B4 07 flux and magnetic properties of Mno"Znoo,Fe,04 synthesized from resultant iron oxide has been investigated.The main purposes of present study are to decrease the heating temperature as much aspossible for reduction of the purifing energy cost, and to examine effects of decrease in heating temperature on iron oxide morphology and removal of Zn, 8, As, and effect of iron oxide purity on magnetic properties of Mno"Zno05Fe204 synthesized from resultant iron oxide.The main results obtained as follow:(l) Morphology of purified iron oxide is returned gradually from hexagon crystals pseudoparticles of original raw material as heating temperature is decreased.(2) From removal of Zn, 8 and As, heating temperature is possible to decrease from 1573K to 1273K.(3) Purity and magnetic properties of iron oxide have nearly no influence on magnetic properties of synthesised Mno95Znoo,FezO, ferrite.
