This collection presents papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Topics include the extraction and processing of elements such as rare earth metals including yttrium and scandium, gold, vanadium, cesium, zinc, copper, tellurium, bismuth, potassium, aluminum, iridium, titanium, manganese, uranium, rhenium, and tungsten. Rare processing techniques covered include supercritical fluid extraction, direct extraction processes for rare-earth recovery, biosorption of precious metals, and recovery of valuable components of commodity metals such as zinc, nickel, and metals from slag.

This collection addresses the pressing needs for sustainable technologies with reduced energy consumption and environmental pollutions and the development and application of alternative sustainable energy to maintain a green environment and efficient and long-lasting energy supply. Contributors represent both industry and academia and focus on new and efficient energy technologies including innovative ore beneficiation, smelting technologies, and recycling and waste heat recovery, as well as emerging novel energy solutions. The volume also covers a broad range of mature and new technological aspects of sustainable energy ecosystems, processes that improve energy efficiency, reduce thermal emissions, and reduce carbon dioxide and other greenhouse emissions. Authors also explore the valorization of materials and their embodied energy including byproducts or coproducts from ferrous and nonferrous industries, batteries, electronics, and other complex secondary materials. 

This collection presents papers from a symposium on extraction of rare metals from primary and secondary materials and residues as well as rare extraction processing techniques used in metal production. The collection covers the extraction of less common or minor metals including elements such as antimony, bismuth, barium, beryllium, boron, calcium, chromium, gallium, germanium, hafnium, indium, manganese, molybdenum, platinum group metals, rare earth metals, rhenium, scandium, selenium, sodium, strontium, tantalum, tellurium, and tungsten. It also includes rare metals of low-tonnage sales compared to high-tonnage metals (iron, copper, nickel, lead, tin, zinc, or light metals such as aluminum, magnesium, or titanium and electronic metalloid silicon). Rare metal processing covers bio-metallurgy, hydro-metallurgy, and electro-metallurgy while novel high-temperature processes such as microwave heating, solar-thermal reaction synthesis, and cold crucible synthesis of rare metals are also addressed. Also included in this collection is the design of extraction equipment used in these processes from suppliers as well as laboratory and pilot plant studies.

This collection is focused on industrial energy sustainability and CO2 management, including processes that improve energy efficiency and reduce or eliminate industrial GHG emissions. Topics address technology areas such as clean energy technologies, innovative beneficiation, smelting technologies, process intensification, as well as CO2 capture and conversion for industrial applications.
