Modelling of Hydrometallurgical Process Solutions With OLI
(Old)
Vladimiros Papangelakis, University of Toronto
Chemical modelling is increasingly becoming a necessary tool in the development, analysis, design, and control of hydrometallurgical processes. The latter involve the application of aqueous chemistry to recover pure metals from mineral deposits. The Mixed Solvent Electrolyte Model of OLI Systems presents a new and robust thermodynamic framework for reliable modelling and simulation of aqueous chemistry from the very dilute to the fused salt range. Dedicated databanks for chemical modelling of selected hydrometallurgical systems have been developed by regression on literature and our own data using the OLI software. Successful modeling examples from hydrometallurgical operations, such as the high pressure acid leaching (HPAL) of laterites, oxygen solubility in the oxidative leaching process of zinc sulfide, gypsum solubility and lead chemistry in mixed sulfate-chloride solutions are presented.
