Abstract :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%.
