[Abstract]
Among the major challenges currently facing the metals and minerals industry are high energy intensity, environmental impact, and potential shortfalls of some mineral resources in particular “critical metals”. These challenges have raised questions about the long-term availability of primary resources and the sustainability of resource recovery processes. To this end, the recovery of critical metals from secondary resources along with the mineral carbonation of industrial wastes has gained interest for reducing reliance on primary resources, mitigating anthropogenic carbon emissions, and enhancing sustainability.
In this talk, I will first discuss innovative technologies to recover critical metals from primary and secondary resources. Various processes such as acid baking ? water leaching, sodium hydroxide cracking, solid-liquid separation, carbothermic reduction, and microwave pretreatment have been developed for efficient metal extraction, separation, and purification. The fundamental chemistry of metallurgical systems is investigated, combining both theoretical and experimental efforts.
The focus of this talk will be expanded to the development of supercritical carbonation processes for carbon dioxide sequestration using industrial wastes. The chemistry of a given system is investigated to predict carbon dioxide uptake and design a suitable carbonation process. Process development and laboratory-scale testing are carried out to investigate the effect of operating parameters and optimize the process.
