Özet
Kömür tanelerinin hidrofobisitesini arttırmak için mazot, gazyağı ve fuel oil gibi yağlar kömür flotasyonunda toplayıcı olarak endüstriyel ölçekte kullanılmaktadır. Bu çalışmada, dört farklı tipte yağın (mazot, fuel oil, orijinal ayçiçek yağı, atık ayçiçek yağı) yüksek kül (%35,65) ve kükürt (%7,91) içerikli toz boyutlu (-0,25 mm) kömürde flotasyon performansı araştırılmıştır. En yüksek yanabilir verim toplayıcı olarak mazot kullanılması durumunda %87,48 olarak elde edilmiştir. En fazla kül giderimi ise %58,36 olarak fuel oil kullanıldığında gerçekleşmiştir. Kömürün flotasyon ile zenginleştirilmesinde, petrol kökenli yağlara alternatif olarak kolay bulunabilen, yenilenebilir bitkisel kökenli yağında kullanılabileceği belirlenmiştir. Ayrıca atık ayçiçek yağının performansının (yanabilir verim %84,19 ve kül giderimi %56,17) diğer yağların performansına yakın olduğu sonucuna ulaşılmıştır.
Oils such as diesel oil, kerosene and fuel oil are used as collectors in coal flotation in order to increase the hydrophobicity of the coal particles. In the current study, the effect of four different type of oils (diesel oil, fuel oil, original sunflower oil, waste sunflower oil) were investigated on flotation performance of a coal in powder form (-0.25 mm) with high ash (35.65%) and sulphur (7.91%) content. Maximum combustible recovery with 87.48% was achieved using diesel oil as the collector. Maximum ash rejection by 58.36% was obtained using fuel oil. It has been determined that it can be used as an alternative to petroleum based oils and can be used as a renewable vegetable based oil in the enrichment of coal with flotation. Furthermore, it was concluded that the performance of waste sunflower oil (combustible recovery of 84.19%, ash rejection of 56.17%) is close to the performance of other oils.
