Tailings Wikipedia. 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

Benson Mines Wikipedia

The Benson Mine is an iron-ore mine located near Star Lake, a village in the southern St. Lawrence County, New York.. The ore body at Benson Mine was discovered in 1810 by engineers conducting a survey for a new military road from Albany to Ogdensburg. In the 1950s, mine was considered the largest open pit iron-ore mine in the world.

May 15, 2017· However, mine tailings may also be recycled and reused, e.g. manganese-rich tailings could be used in agro-forestry, building and construction materials, coatings, cast resin products, glass, ceramics, and glazes (Lottermoser, 2011). Increasing demands for metals, coupled with depleting reserves of high-grade primary ores, has meant that waste

Characterization and Economic Potential of Historic

In contrast to modern tailings from froth flotation, little is known about historic tailings from gravity separation. However, they may be of economic interest due to their higher metal grades compared to modern tailings. As an example for these types of historic tailings, the inner structure, as well as the economic potential (Pb, Zn, Cu, Ag, Sb), of the old Bergwerkswohlfahrt mine waste dump
