The excess sulfur content of coal structure is harmful for the environment and human health. It also causes air pollution. When sulfur is burned SO2 occurs. This shows a toxic effect. For this reason, an excess of S (sulfur) in the coal content is undesirable and the low sulfur content increases the quality of the coal. One of the methods used to reduce the sulfur content in coal content is the chemical enrichment (leaching) method. In this method, the coal sample is treated with a suitable solvent and separated from the undesired impurities in its content. In this study; chemical analysis of coal sample taken from Erzurum-Şenkaya area, is determined % ash,% humidity,% caloric values. Then, chemical methods (leaching) are applied on the coal samples with equal amounts of Sodium Hydroxide and Potassium Hydroxide at 100°C-500 °C at 4 different temperatures. As a result, pyrite (FeS2) in coal structure is disintegrated and FeS2 (pyrite) -indu
