ABSTRACT:
A process for removing mineral matter from feed coal employing liquid carbon dioxide. A water slurry of pulverized feed coal is mixed with liquid carbon dioxide. Demineralized coal is collected in the liquid carbon dioxide phase while separated mineral matter concentrates in the water phase. The two liquid phases are separately drawn off and their solid contents recovered.
