One of the methods used for the enrichment of fine size coal is the magnetic enrichment
method with magnetic separators. The magnetic separators can generally be grouped into wet and dry
magnetic separators. Although this method is not widely used in coal applications, it is applied to remove
the pyrite (FeS2) in the structure of fine-grained coal or to remove the magnetite used as heavy medium
fluid in coal washing plants. In this study; The coal sample used in the experiments was taken from the
coal mine in Balkaya village of Erzurum. According to the chemical analysis, the ash content of the coal
sample taken is 20.38%, the sulfur content is 3.48% and the calorific value is lower heat value is
5342kcal. After the chemical analysis and sieve analysis values of the coal sample were determined, they
were subjected to enrichment at 9000 Gause, 14000 Gause and 19000 Gause magnetic field strength with
high field strength Wet Magnetic Separator (HGMS) on the laboratory scale and the results were
interpreted. When the experimental results were compared between each other, it was found that the best
enrichment was obtained with ash ratio of 17.48% at 19000 Gause field strength. However, when
evaluated in terms of enrichment, the reduction of pyridic (FeS2) sulfur content from Erzurum / Balkaya
coal is not considered economic.
İnce tane boyutlu kömürlerin yıkanması ve zenginleştirilmesinde kullanılan yöntemlerden biri de
manyetik ayırıcılarla yapılan manyetik zenginleştirme yöntemidir. Manyetik ayırıcılar genel olarak yaş ve
kuru manyetik ayırıcılar şeklinde gruplandırılmaktadır. Kömür uygulamalarında çok yaygın kullanılmasa
da, ince taneli kömürün yapısında bulunan piritin(FeS2) uzaklaştırılması veya kömür yıkama tesislerinde
ağır ortam sıvısı olarak kullanılan manyetitin uzaklaştırılması için manyetik ayırma yöntemi
uygulanmaktadır. Bu çalışmada; deneylerde kullanılan kömür numunesi Erzurum’ un Balkaya köyünde
faaliyet gösteren kömür ocağından alınmıştır. Alınan kömür numunesinin kimyasal analizlere göre kül
oranı %20,38 ile kükürt oranı %3,48 ve kalori değeri alt ısıl değeri 5342kcal’dir. Kömür numunesinin
kimyasal analiz ve elek analiz değerleri tespit edildikten sonra, laboratuar ölçekte yüksek alan şiddetli
Yaş Manyetik Seperatör(HGMS)’ de 9000 Gause, 14000 Gause ve 19000 Gause manyetik alan şiddetinde
zenginleştirmeye tabi tutulmuş ve sonuçlar yorumlanmıştır. Deney sonuçları birbirleri arasında
karşılaştırıldığında en iyi zenginleştirmenin 19000 Gause alan şiddetinde %17,48 kül oranı ile elde
edildiği belirlenmiştir. Ancak zenginleştirme açısından değerlendirildiği zaman Erzurum/Balkaya
kömüründen piridik(FeS2) kükürt içeriğinin azaltılması ekonomik görülmemektedir.
