Copper Statistics and Information U.S. Geological Survey
Copper is one of the oldest metals ever used and has been one of the important materials in the development of civilization. Because of its properties, singularly or in combination, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third
Strength and liquefaction assessment of tailings
Ideally a site-specific seismic risk assessment should be completed for high-risk dams. The post liquefaction behaviour of a tailings storage depends on the ratio of available strength to the stresses that are acting. A flow slide is defined as slope instability that results when a soil liquefies, and the disturbing forces exceed the strength.
