site, so long as such modified requirements assure protection of human health and the environment. This report addresses wastes from the extraction and beneficiation of metallic ores (with special emphasis on copper, gold, iron, lead, silver, and zinc), uranium overburden, and the nonmetals asbestos and phosphate rock.
Overburden - Wikipedia
In mining, overburden 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.
Accounting for Increasing Mine Wastes in the . - User Web Pages
There is virtually no waste rock data reported for nickel, lead-zinc-silver, iron ore or bauxite mining, with only a small number of waste:ore ratios available for some years and not the historical record of such data. There is only limited and recent data available for overburden in coal mining, but due to this short history of data.
The outflow of acidic water from metal mines. After being exposed to air and water, oxidation of metal sulfides (often pyrite, which is iron-sulfide) within the surrounding rock and overburden generates acidity. . Backfill.
