SUMMARY
Carbonate leaching is ineffective for thorium dioxide (ThO2) due to its high insolubility in most solvents, with the exception of hot, concentrated sulfuric acid. The discussion clarifies that carbonate complexes primarily involve uranyl VI, while both uranium IV (U IV) and thorium IV (Th IV) remain insoluble. Consequently, since Th IV is already at its maximum oxidation state, a carbonate leach for ThO2 is not feasible.
PREREQUISITES
- Understanding of carbonate leaching processes in uranium chemistry
