Abstract
The fossil properties can be increased via enrichment process. It is the process that removes sulfur and mineral matter without changing the organic structure. In this study, can lignite was demineralized with some mineral free acid of 5% such as HCOOH and some mineral acids of 5% such as HNO3, H2SO4, HCl, H3PO4 and HF after 5% NaOH washing. The best sulfur and mineral matter performed were obtained with NaOH plus HF treatment as approximately 44% and 45%, respectively. FTIR and X ray spectra of the samples were also drawn to determine the functional groups and mineral composition.
