Most tailings can be thickened mechanically, some to a paste or filter cake consistency. However, clay mineral-rich tailings, such as coal tailings, mineral sands tailings, tailings from some oxide ores, and residue from the processing of bauxite, nickel laterite and oil sands, are difficult to dewater mechanically,
