| Abstract: | Froth flotation (FF) pretreatment of coal from Hazro, Turkey, for enhancing desulfurization with sodium hydroxide
was investigated. FF reduced following contents of coal: ash, 58.54; pyritic sulfur, 79.34; and volatile matter, 56.98%. The
coal flotation was 69.59%. FF could not remove organic sulfur. Coal concentration obtained from flotation was leached
using aqueous NaOH and its organic sulfur content was reduced by 59.27%. Hence using combination of two methods, total
sulfur, ash and volatile matter contents was reduced by 88.06%, 63.13% and 77.32%, respectively. |
