Advances in Rhenium Mineralogy, Geochemistry and Industrial Uses

Dear Colleagues,

Rhenium with an average concentration of <1 part per billion is enriched in only few places at the Earth's crust. It is mainly obtained as a by-product of molybdenum and copper refinement from Cu-Mo porphyries and sediment-hosted deposits. Rhenium is among the most expensive metals, with principal application in high-temperature superalloys for use in jet engines. Molybdenite is the major repository of Re in the Earth’s crust. Re-bearing molybdenite with more than 1 wt. % Re, Re-Mo-Cu sulfides and the pure Re-bearing sulfide rheniite have been rarely found in porphyry-style Cu-Mo deposits, in magmatic Cu-Ni deposits and in sublimates of active volcanoes. The purpose of this Special Issue is to intergrate all new information about rhenium mineralogy and geochemistry in diverse types of ores deposits worldwide, highlight the causes of Re-enrichment in various styles of mineralization and present advances on industrial uses of rhenium. On deposit scale, associated ore mineralogy will be tested as a tool for rhenium enrichment and future exploration.
