Arsenic and Gold Mine Tailings FAQ What is arsenic? Arsenic is a natural element that can be found distributed throughout the Earth''s crust. It is found in arsenopyrite, the same rock in which gold is often embedded. Many areas of Nova Scotia have elevated arsenic levels, not just the gold mine tailing sites.
Arsenic is a common element in the natural environment and is frequently a significant component in gold deposits of the western United States. Such deposits contain various forms of arsenic: arsenides, sulfides, and sulfosalts. Upon weathering such minerals routinely lower the pH of nearby waters, mobilizing arsenic and other metals. Arsenic may also be mobilized in aqueous environments where ...
