Overburden - Wikipedia

In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an ex

Sep 01, 2008  Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (waste-to-ore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining throughout the country.

In surface mining, the overburden will be removed and dumped aside, thus waste produced will be much higher than the coal or ore extracted based on stripping ratio. Almost every coal as well as metal mining produces waste rock. The quantity of waste produced (shale and sandstone) in coal mines is in-terms of millions of cu.m per year.
