Rhenium. Rhenium (element #75, symbol Re) is a rare, silvery-white metallic element. Rhenium is found as a trace element in platinum ores and in the mineral columbite. It is very dense and has a melting temperature of degrees C ( degrees F). Rhenium is mostly exported in the form of metal pellets with % purity. At least 90% of these exports go to the United States. Essentially 70% of the world’s Rhenium is used in the manufacture of super alloys that are mostly used in jet engine aircraft turbine alloys.
Founded in in Elyria, Ohio (near Cleveland), Rhenium Alloys, Inc. began business with a single product line: the highest quality fine gage rhenium wire available in the marketplace. Since then, Rhenium Alloys, Inc. has added related refractory metal product lines and created several new materials and tools, while maintaining its dedication. United States of America 1 10/37 () Book. Jan ; Robert B. Ross but several such catalysts are now available. Rhenium activated catalysts have many advantages over.
Rhenium sits two places below manganese in the periodic table and its existence was first predicted by Mendeleev when he first proposed his periodic table in In fact this group is unusual. Rhenium has the highest boiling point of any element and the third-highest melting point. This intense resistance to heat gives rhenium strength and stability in high-temperature applications, and prevents it from warping while in use. For this reason, rhenium is commonly used in combination with nickel and the alloys are used to build jet engines.

Bureau of Mines, (OCoLC) Material Type: Government publication, National government publication: Document Type: Book: All Authors. Rhenium (Re), the last naturally-occurring element to be discovered, was discovered in Germany in The process was so complicated and the cost so high that production was discontinued until early when tungsten-rhenium and molybdenum-rhenium alloys were prepared.
These alloys found important applications in industry that resulted in a great demand for the rhenium. Rhenium does not occur free in nature or as a compound in any distinct mineral; instead it is widely distributed in small amounts in other minerals, usually in concentrations averaging about parts per million.
Chile is the world leader in rhenium recovery, followed by the United States, Poland, Uzbekistan, and Kazakhstan. Rhenium occurs up to about 20 parts per million in molybdenite.

Commercial rhenium in the U.S. today is obtained from molybdenum roaster-flue dusts obtained from copper-sulfide ores mined in the vicinity of Miami, Arizona and elsewhere in Arizona and in Utah.
Some molybdenum contains from % to % rhenium. More thantroy ounces of rhenium are now being produced yearly in the United States. T.R. Crompton, in Determination of Metals in Natural Waters, Sediments and Soils, Rhenium. Rhenium is one of the rarest elements in the earth’s crust, possessing an abundance of approximately 1 μg kg − abundance of rhenium has been established at about μg L − has been established that the perrhenate ion Re Viii O 4 −, is the only significant rhenium species.
Rhenium is one of the rarest elements in Earth’s continental crust; its estimated average crustal abundance is less than 1 part per billion. Rhenium is a metal that has an extremely high melting point and a heat-stable crystalline structure.
More than 80 percent of the rhenium consumed in the world is used in high-temperature superalloys, especially those used to make turbine blades for jet. Availability of rhenium in the United States.

Molybdenite is a gray, metallic mineral. found in veins and disseminated in most. Of the rhenium used in the U.S. inthe USGS (United States Geological Survey) estimates that 20% (15% worldwide) was used in petroleum-reforming catalysts. Bimetallic platinum-rhenium. This data release provides descriptions of more than mining districts, mines, and mineral occurrences (deposits and prospects) within the United States that are reported to contain enrichments of rhenium (Re).
These mineral occurrences include mined deposits, exploration prospects, and other occurrences with notable concentrations of rhenium. Rhenium is an element in the transitional metals grouping.
It is the last discovered naturally occurring, stable element. Rhenium was found in Germany by Walter and Ida Noddack around Dimitri Mendeleev predicted the placement of the element in although it wouldn’t be discovered for more than a decade.
Rhenium resembles manganese chemically and is obtained as a by-product of molybdenum and copper refinement. Rhenium shows in its compounds a wide variety of oxidation states ranging from 1 to +7.
Rhenium diboride (ReB2) is a hard compound having the hardness similar to that of tungsten carbide, silicon carbide, titanium diboride or zirconium.
Current total Rhenium resources in the United States are approximately 5 million kg. Pebble’s total Rhenium endowment represents an 84% increase to the nation’s known Rhenium resource base. Listed below are links to chapters from the Minerals Yearbook (Volume I Metals and Minerals).
These annual reviews contain statistical data and information on approximately 90 commodities. They detected rhenium spectroscopically in platinum ores and in the minerals columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6), gadolinite ((Ce, La, Nd, Y) 2 FeBe 2 Si 2 O 10) and molybdenite (MoS 2).
Rhenium is present in these materials only in trace amounts. InNoddack and Berg were able to extract 1 gram of rhenium from kilograms of molybdenite.
Yes you guessed it, it was rhenium, or rather a rhenium compound namely the rhenium ion, [Re2Cl8]2+ [correction: this should be the two minus ion, not the two plus ion]. More recently an especially simple compound of rhenium, rhenium dibromide, has attracted a great deal of scientific attention because it is one of the hardest of all known.

According to the USGS, some 8, kg of Rhenium was produced at six US operations in However, the United States also impor kg - more than 82% of its current needs. Rhenium is used mainly in superalloys for turbine engines and for petroleum reforming catalysts, and demand is expected to grow.COVID Resources.
