ENRICHMENT STUDIES OF IRON ORE IN S？VAS REGION WITH DRY MAGNETIC SEPARATION AND PROPER PLANT DESIGN

In this study, strategies for enrichment of iron ore samples of Demir Export A.？. via conventional magnetic separation were evaluated. Fe% and SiO2 % of the iron ore used in the study is measured as in between 53.20-53.78 and above 10.5, respectively. Also, Al2O3 content is 2.3% and total alkali content (K2O + Na2O) is over 0.6%. Fe content of the ore meet the basic market sales requirements. On the other hand, silica, alumina and alkali contents are close to or slightly above the value defined as rejection limit. Experimental studies have been carried out in order to overcome these problems, especially the impurity content. Considering the current production method, it has been determined that the developed method should be a dry separation method, and therefore dry magnetic separation tests were planned and carried out. In addition, heavy liquid tests have been applied to reveal the best quality products that can be produced from the ore. Experimental studies have shown that 68% (61.26% Fe) and 92% (55.39% Fe) of products can be obtained from size fractions of -30 + 10 mm and -10 mm, respectively
