Scope The symposium will cover extraction of rare metals from primary and secondary sources. Rare metals include strategic metals that are in increasing demand and subject to supply risks (those that are not covered by other TMS symposia). The focus of this symposium will be on rare earth metals including neodymium, dysprosium, scandium and others; platinum group metals including platinum, palladium, iridium, and others; battery related metals including lithium, cobalt, nickel, and aluminum; electronics related materials including copper and gold; and refectory metals including titanium, niobium, zirconium, and hafnium. Other critical materials, such as gallium, germanium, indium and silicon are also included.
The focus of the symposium will be on primary production as well as secondary production through urban mining and recycling to enable the circular economy.
This symposium covers various processing techniques, including but not limited to, hydrometallurgy (solvent extraction, ion exchange, precipitation and crystallization), electrometallurgy (electrorefining and electrowinning), pyrometallurgy, and aeriometallurgy (supercritical fluid extraction). Presentations are welcomed to address topics on process development, process control, process modelling, and environmental issues.
