The particle-size distribution graph plots percent finer by weight vertically against particle diameter d in millimetres horizontally for C o T and C o P. The horizontal axis uses a logarithmic scale from 0.001 to 1.000 millimetres. The vertical axis ranges from 0 to 100 per cent in intervals of 10 per cent. C o T is marked by open triangles and C o P by filled circles. Both curves increase with particle diameter. C o T rises gradually from about 3 per cent near 0.001 millimetres to about 31 per cent near 0.03 millimetres, 47 per cent near 0.08 millimetres, 57 per cent near 0.10 millimetres, 68 per cent near 0.15 millimetres, 81 per cent near 0.21 millimetres and 92 per cent near 0.30 millimetres, reaching approximately 100 per cent beyond 0.5 millimetres. C o P rises from about 2 per cent near 0.001 millimetres to about 19 per cent near 0.03 millimetres, then increases more steeply through about 35 per cent near 0.06 millimetres, 42 per cent near 0.08 millimetres, 70 per cent near 0.11 millimetres, 88 per cent near 0.15 millimetres and 97 per cent near 0.21 millimetres, reaching approximately 100 per cent near 0.3 millimetres. Embedded views associated with the curves contain cylindrical specimens of different proportions, loose granular material and compact cylindrical material samples.Particle size distribution of the total copper tailings samples
