Nickel is found naturally in both food and water, and may be increased by human pollution. For example, nickel-plated faucets may contaminate water and soil; mining and smelting may dump nickel into waste-water; nickel–steel alloy cookware and nickel-pigmented dishes may release nickel
The PolyMet NorthMet open pit copper-nickel mine would be Minnesota's first non-ferrous mine. It would include three new open pits, permanent and temporary waste rock heaps, and a permanent tailings waste dump and highly toxic hydrometallurgical residue in Minnesota's St. Louis River watershed in the Lake Superior Basin.
Advances in technology allow lower grade ores to be exploited, generating higher volumes of waste that require safe storage. Environmental regulations are also advancing, placing more stringent requirements on the mining industry, particularly with regard to tailings storage practices.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

nickel is providing a much-needed reprieve for the industry as a shift towards nickel-rich battery chemistries accelerates. Currently, class 1 nickel supply suitable for battery production represents approximately half of global supply of 2.1 million metric tons (Mt) – although only 350 metric kilotons (Kt)
TENORM: Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
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.
