Recovery of Soluble Potassium from Alunite by Thermal Decomposition: Effect of CaO and Phase Transformation
As mining waste, alunite is a potential resource to produce potassium salt. The decomposition of alunite is closely associated with the recovery of soluble potassium. In this study, the effect of CaO on phase transformation of alunite in the desulfation stage was examined. The results showed that Ca...
