Copper - British Geological Survey

Copper is a non-ferrous base metal and its average concentration in the earth's crust is about 50 ppm (parts per million). The average minimum exploitable grade for a copper deposit is 0.4% which equates to a concentration factor of around 80 based on average crustal abundance. Copper occurs naturally in all plants and animals, as it is
