Recovery of coal from waste fine coal by column flotation

This study involved enriching by means of a laboratory-scale column flotation apparatus waste coal dust obtained from the Zonguldak coals. The effect of the factors such as the amount of the frothing agent, the amount of collecting agent, the feeding height, the thickness of the froth, the column height and the air rate on the coal yield was investigated and attempts were made to determine the efficiency level that would give the highest yield. Furthermore, in order to get the desired yield from column flotation, the most appropriate value was established for each variable under study in terms of ash content and yield, and a column flotation experiment was carried out under optimal conditions. It was established that through the column flotation of waste fire coal having an ash content of 53.35%, a volatile matter content of 19.20%, a fixed carbon content of 27.45%, a total sulfur content of 0.74% and a calorific value of 14.42MJ/kg, clean coal could be recovered whose concentrate weight yield would be 32.06%, combustibility yield 61.16% and ash content 11.15%.
