Thermodynamic parameters of reactions of basic copper carbonates formation with participation of organic complexing agents

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.
