Abstract The research include the capability of Iraqi iron ore concentration which is available in AL - GARAA region by wet magnetic separation method after Hematite ore reduction to ( magnetite ) by magnetic roasting method , and after studying some variables which are the roasting temperature , the roasting time , the coal quantity that is added for completion of reduction operation it had been cleared that greater percent of separated iron concentrate was 85 % at 760 ° c and the time of roasting was ( 15 ) min . and coal roasting quantity was ( 1 ) gm with stabling of other variables which are impeller speed of wet magnetic separation instrument which was ( 250 ) cycle / min , and the time of separation was ( 10 ) min , and the particle size was ( 25 ) micron , and the quantity of separation water for ( 1 ) jet was ( 500 ) milliliter .
