Thermodynamic Description of Oxidized Zinc Minerals and Comparative Analysis of Their Reactivity

Due to depletion of sulfide zinc ores, the problem of involvement of economically significant oxidized zinc ores into the treatment is a vital task. In this article, the thermodynamic functions have been considered and determined for many oxidized zinc minerals, such as calamine, smithsonite, willem...
