Rare Metal Technology 2023

Collection Overview

This collection presents papers from a symposium on extraction of rare metals from primary and secondary materials and residues as well as rare metals extraction processing techniques used in metal production.

Metals Covered

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).

Processing Techniques

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.

Additional Content

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.
