In this study, the washability features Kahramanmaraş-Elbistan lignite
was investigated. Experimental studies were carried out with the lignite
samples taken from Kahramanmaraş-Elbistan in Turkey. Firstly, float-sink test
were made on -31.5+19 mm, -19+4.75 mm
and -4.75+0.5 mm particle size fractions. Then, assessment of the washability
features was made by using washability number (W), index of washability (WI)
and near gravity material index (NGMI). It has also been attempted to find out
whether it is easy or difficult to enrichment Elbistan lignite with gravity
methods by using washability index methods. From all these calculations, it is
concluded that Elbistan lignite is very difficult to wash and gravity
enrichment, only it to be washed under control at a certain density (1,55-1,65
g/cm3).

Bu çalışmada, Kahramanmaraş-Elbistan linyitinin yıkanabilirlik
özellikleri araştırılmıştır. Bu amaçla sahadan alınan linyit örneğinden
-31,5+19 mm, -19+4,75 mm ve -4,75+0,5 mm olmak üzere 3 ayrı boyutta
yüzdürme-batırma deneyleri gerçekleştirilmiştir. Daha sonra yıkanabilirlik
sayısı (W), yıkanabilirlik indeksi/Govindarajan indeksi (WI/GWI) ve yakın
yoğunlukta malzeme indeksi (NGMI) gibi farklı yıkanabilirlik indeksleri
kullanılarak, Elbistan linyitinin karşılaştırmalı olarak yüzebilirlik özelliği
ve gravite yöntemleri ile zenginleştirilmesinin kolay veya zor olacağı ortaya
çıkarılmaya çalışılmıştır. Tüm bu hesaplamalardan Elbistan linyitinin
yıkanabilirliğinin ve zenginleştirilmesinin çok zor olduğu, sadece belirli bir
yoğunluk aralığında (1,55-1,65 g/cm3)
kontrollü olarak yıkanması gerektiği sonucuna varılmıştır.
