    Chile has the world's largest rhenium reserves, part of the copper ore deposits, and was the leading producer as of 2005. [44] It was only recently (in 1994) that the first rhenium mineral was found and described, a rhenium sulfide mineral (ReS 2) condensing from a fumarole on Kudriavy volcano, Iturup island, in the Kuril Islands.

    They also found rhenium in gadolinite and molybdenite. [5] In 1928 they were able to extract 1 gram of the element by processing 660 kg of molybdenite. In 2020 a memorial medal of the discovery was issued by ISTR (art-designer: Igor Petrov).

    It is found in low concentrations with many other metals, in the ores of other refractory metals, platinum or copper ores. It is useful as an alloy to other refractory metals, where it adds ductility and tensile strength. Rhenium alloys are being used in electronic components, gyroscopes and nuclear reactors. Rhenium finds its most important ...

    Rheniite is one of the first minerals of the element rhenium to be found. The other known approved rhenium mineral is the sulfide mineral tarkianite. Almost all commercially mined rhenium is retrieved as a by-product of molybdenum mining as rhenium occurs in amounts up to 0.2% in the mineral molybdenite. A discredited rhenium sulfide known as ...

    Perey discovered it as a decay product of 227 Ac. [182] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.
