Abstract

An aqueous coal suspension contains two separate groups of coal particles, preferably with the particles of the first group having an average size of from 210 to 60 mu m, the maximum size not exceeding 300 mu m, and the particles of the second group having an average size of from 1/6 to 1/20 of the average size of the particles of the first group. When plotted on a bilogarithmic scale, the cumulative particle size distribution curve (see for example Figure 1) has a flat zone lying between the values representing the average sizes of the two groups of coal particles. In addition to coal and water, the suspension contains a non-surface active anionic polyelectrolyte having a molecular weight exceeding 500, and possibly a stabiliser of the organic gel type.
