This patent describes coal-water slurry compositions consisting of: (a) from about 50% to about 85% of finely divided coal particles having a particle size such that substantially none of the particles has a size greater than 4 Tyler mesh; (b) from about 0.01% to about 5.0% of sulfated O-glycosides having the formula RO(R'O)/sub t/-(Z)/sub x/-(SO/sub 4/M)/sub n/ wherein R is selected from the group consisting of substituted and unsubstituted aliphatic and aromatic hydrocarbons having from 6 to about 32 carbon atoms, wherein the substituents are nonionic groups consisting of carbon, hydrogen, oxygen and combinations thereof, R' is selected from substituted and unsubstituted alkyl groups having from 2 to 4 carbon atoms, wherein the substituent is hydroxy, t is a single number or distribution of numbers from 0 to about 30, Z is the residue of a reducing monosaccharide, x is a single number or distribution of numbers from 1 to about 10, n is a single number or distribution of numbers from 1 to 3x+1, and M is an inorganic or organic cation; and (c) from about 10% to about 50% water.
