Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, 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
The Palabora open pit. The very competent rock allows the pit walls to be cut much steeper than is normal in open pit mining. Loading in the open pit, the bottom of which is now over 230m below sea level.
Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses.
