(a) Coarse grain tailing size is 0-0.075 mm, and fine grain tailing size is 1-2 mm. (b) Coarse grain tailing size is 0-0.075 mm, and fine grain tailing size is 0.5-1 mm. (c) Coarse grain tailing size is 0-0.075 mm, and fine grain tailing size is 0.3-0.5 mm. (d) Coarse grain tailing size is 0-0.075 mm, and fine grain tailing size is 0.25-0.3 mm. (e) Coarse grain tailing size is 0.075-0.1 mm, and fine grain tailing size is 1-2 mm. (f) Coarse grain tailing size is 0.075-0.1 mm, and fine grain tailing size is 0.5-1 mm. (g) Coarse grain tailing size is 0.075-0.1 mm, and fine grain tailing size is 0.3-0.5 mm. (h) Coarse grain tailing size is 0-0.075 mm, and fine grain tailing size is 0.25-0.3 mm. (i) Coarse grain tailing size is 0.1-0.15 mm, and fine grain tailing size is 1-2 mm. (j) Coarse grain tailing size is 0.1-0.15 mm, and fine grain tailing size is 0.5-1 mm. (k) Coarse grain tailing size is 0.1-0.15 mm, and fine grain tailing size is 0.3-0.5 mm. (l) Coarse grain tailing size is 0.1-0.15 mm, and fine grain tailing size is 0.25-0.3 mm. (m) Coarse grain tailing size is 0.15-0.25 mm, and fine grain tailing size is 1-2 mm. (n) Coarse grain tailing size is 0.15-0.25 mm, and fine grain tailing size is 0.5-1 mm.
