RESEARCH ON WASHABILITY OF STOCK COAL OF SEYITOMER
Abstract
A coal consisting some part of lignite producing from Seyitömer coal basin with low calorific value (approximately 1200-1300 kcal/kg) and high clay content is called as stock coal. Researches to increase quality of this coal, cause environmental problem and has not economic income, have become significance. For this purpose investigation of washability of stock coal was carried out at the present study. At the first stage of the study removal possibilities of clay disturbing medium condition and lowering the calorie was investigated. At the second stage, -100+18 and -18+5 mm fractions of coal were exposed to sink and float tests in 1.4 and 1.7 gcm-3 separately. At the result of the experimental study clean coal has 23.05 % ash content and 2810 kcal/kg combustible matter recovery was obtained by floating the fraction of -100+18 and -18+5 mm in 1.4 gcm-3. also middlings have 32.72 % ash, 2000 kcal/kg calorie with 17.24 % combustible recovery and tailing has 65.95 % ash content were obtained by floating the sinked coal in 1.7 gcm-3.
