Depending on the nature of the ore and min eral processing, dust from mine tailings could contain a number of substances that may pose a health hazard (, lead, arsenic, cad mium, zinc, selenium, mercury, manganese, boron, etc.). Lead can have an adverse health impact particularly to the nervous system of children and the unborn.
Impoundments at the few mills that remain operational and all future tailings impoundments must be built and operated to comply with the regulatory requirements of both the EPA and the NRC (or an NRC Agreement State).
Tailings Dams: Where Mining Waste is Stored Forever. Now imagine that pit filled with up to 10 billion tons of tailings — waste that's derived from mining — that will remain there forever. It's a reality that isn't exactly farfetched. If a large — and controversial — copper mine is built in Alaska's Bristol Bay,...

Prospect of growth intensifies debate about PolyMet tailings dam. "You keep them where they are already present." PolyMet doesn't plan to mine taconite. It would be the first to mine copper, nickel and other precious metals from a massive, untouched deposit east of the Iron Range, creating 300 jobs.
Ores that contain copper in the are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
