Abstract

In this study, the dissolution kinetics of ulexite, a sodium-calcium-borate hydrate (Na₂O·2CaO·5B₂O₃·16H₂O) in citric acid solutions was investigated in a batch reactor. The rate of dissolution can be expressed according to surface chemical reaction controlling with changing fluid reactant concentration. The activation energy of the process was found to be 39.4 kJ/mol.
