Abstract:
In the article some of thermodynamic parameters for the processes which are possible in nature during the
formation of the malachite and azurite are described. The authors have shown that the formation of basic carbonates
from copper sulfide ores is thermodynamically more favorable than that from its oxide minerals. The
presence of complexing agents promote the dissolution of oxide forms of copper and involve its ions into
secondary mineralogenesis. It is found that the hydroxy acids largely promote the formation of a malachite
and azurite than the similar amino acids.
