摘要： An integrated method of removing alkali metal compounds from sulfur-bearing coal is disclosed. The coal is comminuted (4) and mixed (10) with water (8) to form a slurry (12). In the preferred embodiment, the slurry (12) is comingled with an SO.sub.2 -bearing gas (16) in a transport pipeline (52) to form an acidic slurry which dissolves the alkali compounds out of the coal. The slurry is then separated (22) into a solid portion (24) and a liquid portion (26), the solid portion (24) being combusted (34) to form the SO.sub.2 -bearing gas (16).
