Abstract
A process for improving the efficiency of coal dewatering and deashing uses complexing agents such as sodium gluconate in alkaline solution to form soluble compounds with cations such as Al.sup.+3, Fe.sup.+3, Mg.sup.+2, and Ca.sup.+2. The formation of such compounds reduces the adsorption and/or desorbs clay slimes from the coal surface.
