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).

Copper Leaching from Refractory Flotation Tailings

Copper Leaching from Refractory Flotation Tailings

copper sulfide and free oxidation copper in the raw ore were recycled by flotation, but the other refractory copper oxides, mainly the combination copper oxide, were not thoroughly recycled and the majority were lost in the tailings. As is typical for flotation tailings containing silicate gangue minerals, high temperature leaching was used [12].

Tailings

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining
