Türkiye'nin ham petrol ithalatına %90, doğal gaz ithalatına %99 ve kömür ithalatına %95 oranında bağımlı olduğu bilinmektedir. Türkiye'nin en önemli enerji kaynağı yaklaşık 20 milyar ton olan linyitlerdir. Enerjide dışa bağımlılığın yüksek olmasına rağmen, Türkiye'nin elektrik üretiminin yalnızca %14,21'i yerli linyit kaynaklarından elde edilmektedir. Yerli linyitlerden çok düşük miktarda elektrik elde edilmesinin başlıca nedenlerinden biri, bu rezervlerin önemli bir kısmının düşük ranklı olması, yüksek kül ve yüksek kükürt içeriğine sahip olması ve arıtılmadan kullanıldığında ciddi çevre sorunlarına yol açmasıdır.
Bu çalışmada, düşük ranklı linyitlerin kül içeriğini azaltarak santrallerde kullanımını artırmak için bir dizi flotasyon deneyi gerçekleştirilmiştir. Deneylerin tasarımı, deneysel sonuçların analizi ve matematiksel modellerin oluşturulması Merkezi Kompozit Tasarım Yöntemi kullanılarak yapılmıştır. Deneysel sonuçlar, numunelerin kül içeriğinin %52,47'den %29,37'ye düştüğünü ve yanıcı geri kazanımının %32,50 olduğunu ortaya koymuştur.

The most important energy resource of Turkey is lignites which counts for about 20 billion tones. Despite the high external dependency on energy, only 14.21% of Turkey's electricity production is obtained from domestic lignite resources. One of the main reasons why very low amounts of electricity are received from domestic lignites is that a significant portion of these reserves are low-rank, have high ash and sulfur content, and cause severe environmental problems if utilized without purification.
In this work, to reduce the ash content of these lignite’s thus increasing their utilization in power plants, a series of flotation experiments were carried out. Designing experiments, analysing experimental results, and creating the mathematical models were performed using the Central Composite Design Method. The experimental results revealed that the ash content of the samples was reduced from 52.47% to 29.37% with a combustible recovery of 32.50%.
