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). [6] [7]

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 ...
Rhenium has one stable isotope, rhenium-185, which nevertheless occurs in minority abundance, a situation found only in two other elements (indium and tellurium). Naturally occurring rhenium is only 37.4% 185 Re, and 62.6% 187 Re, which is unstable but has a very long half-life (~10 10 years).
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 ...
It is the raw material for all rhenium compounds, being the volatile fraction obtained upon roasting the host ore. [26] Rhenium, in addition to the +4 and +7 oxidation states, also forms a trioxide. It can be formed by reducing rhenium(VII) oxide with carbon monoxide at 200 C or elemental rhenium at 4000 C. [27] It can also be reduced with ...
