Application

Basic copper carbonate refers to the compound (Cu2(OH)2CO3) (the mineral malachite). Sometimes the name is used for Cu3(OH)2(CO3)2 (the related mineral azurite). Malachite and azurite can be found in the verdigris patina that is found on weathered brass, bronze, and copper. The composition of the patina can vary, in a maritime environment depending on the environment a basic chloride may be present, in an urban environment basic sulfates may be present.
The compound Copper(II) carbonate CuCO3 is not known to occur naturally. There is a report from 1973 of the production of CuCO3 from CuO or Cu3(CO3)2(OH)2 in the presence of carbon dioxide at 500°C and 20 kb (2 GPa) pressure. What is often called copper(II) carbonate or cupric carbonate is actually basic copper carbonate.
