Rare metal technology 2015 : proceedings of a symposium sponsored by the Minerals, Metals & Materials Society (TMS) held during TMS 2015, 144th Annual Meeting & Exhibition, March 15-19, 2015, Walt Disney World, Orlando, Florida, USA

This collection presents the papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Paper topics include the extraction and processing of elements like antimony, arsenic, calcium, chromium, hafnium, gold, indium, lithium, molybdenum, niobium, rare earth metals, rhenium, scandium, selenium, silver, strontium, tantalum, tellurium, tin, tungsten, vanadium, and zirconium. Rare processing techniques presented include bio leaching, molecular recognition technology, recovery of valuable components of commodity metals such as magnesium from laterite process wastes, titanium from ilmenites, and rare metals from wastes such as phosphors and LCD monitors.
