Tailings

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

Mine Tailings Disposal Methods

In the past, mill tailings have been discharged onto hillsides or directly into lakes or streams. These practices are now prohibited by state and federal laws. Today, the universal disposal method for tailings is the tailing pond. Tailings are slurried with water and pumped to tailing ponds for settling.

Ultramafic mine tailings are able to sequester CO 2 to form hydrated magnesium carbonates.. Kinetic tests were used to evaluate the weathering of ultramafic mine tailings. The brucite content is the main parameter controlling the maximum CO 2 uptake by the tailings.. The carbonation capacity of the studied tailings vary from 8.5 to 33.6 kg CO 2 /t..
