Abstract
A method for facilitating the flow of material in fines. The fines are selected from silica based materials and coals; and the level of impurity in the fines and comprising metal oxide, carbonate and sulphides in the case of silica materials, and coal ash in the case of coals, is determined. A thick slurry of the fines in water is prepared, and a quantity of dispersant proportional to the determined level of impurity is added to the slurry to form a pumpable slurry.
