In this study, strategies for enrichment of iron ore samples of Demir Export A.Ş. 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.
