Five kinds of coals were pretreated in methanol solution at an ambient temperature. Untreated and treated coals were ground in a boll mill. The ground coal samples were observed and analyzed with CCSEM. Mineral matters were effectively liberated from organic matters by the methanol pretreatment. A centrifugal separation was conducted. Organic matter recovery and mineral matter reduction were improved by the pretreatment.
