Tailings are, by definition, fine-particle residues of milling operations that are devoid of metal values. Particle-size distribution is one of the most important ways of characterizing tailings. The mining industry distinguishes “sands” and “slimes” as components of tailings (usually + 200 mesh, 74 µ, for sands). Gold losses to tailings is the most important parameter in deciding whether a deposit or milling process is economically viable or not.
