“…There are important flotation applications in different countries around the world such as the United States, Australia, China, India, Germany, and Russia (Bentli, 2000). Various studies have been conducted on the coal production process with low ash and sulphur (Atak and Onal, 1991;Ozbayoğlu and Bilgen, 1997;Steel and Patrick, 2001;Karaca and Onal, 2003;Sonmez et al, 2005;Dash et al, 2007). In these studies, the efficiency of acid/base leaching methods was investigated besides flotation to reduce the ash and sulphur content of coal, and significant results were obtained from these studies.…”

Coal has been one of the most important fossil fuels meeting the world`s commercial energy demand for decades. The use of coal in electricity production is an inevitable alternative for developing countries such as Turkey. This study focused on the cleaning process of Zonguldak coal for the production of low ash, low sulphur, and high-calorie coal concentrate. Flotation and atmospheric/autoclave leaching experiments were applied for this purpose. A product with 1% ash, 0.37% sulphur and 8390 kCal/kg of calorific value was obtained under the best experimental conditions.
