Copper ore

Copper is a red to reddish-brown, soft, ductile and malleable metal. Its color as copper red is best seen by reflected light. It is extremely tough, therefore, capable of being drawn out into exceedingly fine wires or hammered out into thin leaves. Its ductility and malleability are greatly diminished by the presence of impurities. As an electrical conductor it is second only to silver.

The metal slowly tarnishes in dry air but in a moist atmosphere it is readily coated with a basic green carbonate. It is readily soluble in the mineral acids. Its specific gravity is 8.9. Its melting point is 1083 C.
