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.eninfo:eu-repo/semantics/closedAccessCoalDemineralizationDesulfurizationFroth FlotationLeachingSodium HydroxideSulfurArticle6617274WOS:0002434516000102-s2.0-33846433758Q2Q3
