Beneficiation of tailing of tunçbilek thickener's undersize by column flotation method

The aim of this is regain of unburned carbon found in sample taken from tailing dam ofTunçbilek Thicknerr undersize buy using the column flotation method. Literature study aboutunder thickener sample and flotation columns had been given before the experiments werestarted.Solid ratio %, frother (MIBC) amount, collector (gas oil) amount, depressant (glasswater) amount, superficial gas velocity, superficial feed velocity, superficial wasting watervelocity, bias and hold-up experiments were carried out to determine optimum condition offlotation column.The unburned carbon was regained from the sample with the 18.88 % ash ratio, 6400kcal/kg calorie and 62.93 % combustible matter recovery in the enlighten of experimentalresults.Key words : Calorie value, glass water, flotation, flotation column, gas oil, MIBC, unburnedcarbon, recovery.
