  • Tailingsfo What are tailings? Their nature and production

    Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).

    Feb 28, 20140183;32;Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. The composition of tailings is directly dependent on the composition of the ore and the process of mineral extraction used on the ore.
