Abstract

It is shown that dewatering of fine coal particles (D₅₀ = 21 μm) is enhanced near the point-of-zero-charge. The coal surface is modified by the addition of copper ions and by adjusting the pH to precipitate surface-active metal hydroxy species, which promote agglomeration and produce low-moisture cakes. Filtration kinetics data are used in calculating filter cake parameters from an integrated form of Darcy's law. The influence of copper ions and pH on filter cake parameters and the correlations among them are presented.
