Rhenium was the last element to be discovered having a stable isotope. The existence of a yet undiscovered element at this position in the periodic table had been predicted by Henry Moseley in 1914. In 1925 they reported that they detected the element in platinum ore and in the mineral columbite. They also found rhenium in gadolinite and ...
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 ...
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).

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.

Rhenium is the most recently discovered refractory metal. 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 ...
The first Serbian feature film, thought lost since 1928. Material from this movie was found in Austrian Film Archives in 2003. [18] Pictureland: Thomas H. Ince: Isabel Rea. King Baggot. The film was rediscovered by a researcher, Robert Hoskin, in Australia who received a print from Japan in 2015 and personally restored it over a course of one year.
Ida Noddack was nominated three times for the Nobel Prize in Chemistry due to her discovery of rhenium and masurium. Noddack and her husband were repeatedly nominated for the Nobel Prize in 1932, 1933, 1935 and 1937 (once by Walther Nernst and K. L. Wagner for 1933; both Noddacks were nominated by W. J. Müller for 1935 and by A. Skrabal for ...
