Abstract

A method of filtering an aqueous slurry containing a mixture of siliceous gangue together with coal and/or a water-insoluble mineral ore is carried out in the presence of a wetting agent (in an amount of 0.2 to 2.0 pounds per ton [0.09 to 0.88 kg/tonne] based on the solids weight of the slurry) and guar gum (in an amount of 0.05 to 0.5 pounds per ton [0.02 to 0.22 Kg/tonne] based on the solids weight of the slurry). It has been found that the above combination of wetting agent and guar gum reduces the moisture content of the filtration residue more than the additive effect of the two components.
