Tailings - Wikipedia

Tailings 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 without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining,Mine Tailings - an overview | ScienceDirect Topics,Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content. Tailings are transported from the mill and are discharged into an impoundment as a slurry containing ∼30 wt.% solids.Tailings - riotinto,Tailings storage facilities follow one of three wall construction designs, or hybrids of these.
