Abstract

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.

Abstract

Bu çalışmada, Demir Export A.Ş.’ye ait demir cevheri numunesinin konvansiyonel manyetik
ayırma ile zenginleştirmesine yönelik stratejiler değerlendirilmiştir. Çalışmada kullanılan demir
cevheri %53,20-53,78 Fe içeriğine sahip olup, SiO2 içeriği %10,5’in üzerinde ölçülmüştür. Al2O3
içeriği ise %2,3’ün, toplam alkali içeriği (K2O+Na2O) ise %0,6’nın üzerindedir. Bu özellikleri ile
cevherin satışlara temel teşkil eden analiz değerleri, Fe içeriğini sorunsuz olarak sağlamaktadır.
Fakat silis, alümina ve alkali içerikleri red sınırı olarak tanımlanan değere çok yakın ya da bir
miktar üzerinde olmaktadır. Deneysel çalışmalar özellikle impürite içeriğinin çıkardığı bu
sorunları gidermeye yönelik olarak gerçekleştirilmiştir. Mevcut üretim yöntemi göz önüne
alınarak geliştirilen yöntemin kuru bir ayırma yöntemi olması gerekliliği belirlenmiş ve bu nedenle
kuru manyetik ayırma testleri planlanmış ve yürütülmüştür. Ayrıca cevherden üretilebilecek
en kaliteli ürün özelliklerini ortaya koyabilmek amacıyla ağır sıvı testleri de uygulanmıştır.
Deneysel çalışmalar sonucunda -30+10 mm ve -10 mm fraksiyonlarında sırasıyla ağırlıkça %68
(%61,26 Fe) ve %92 (%55,39 Fe) oranında ürünler alınabileceği belirlenmiştir.
