Swedish iron ore

A. M. del Rio in 1801 claimed to have discovered the previously unknown element 23 in a sample of Mexican lead ore and, because of the red colour of the salts produced by acidification, he called it erythronium. Unfortunately he withdrew his claim when, 4 years later, it was (incorrectly) suggested by the Frenchman, H. V. Collett-Desotils, that the mineral was actually basic lead chromate. In 1830 the element was rediscovered by N. G. Sefstrom in some Swedish iron ore. Because of the richness and variety of colours found in its compounds he called it vanadium after Vanadis, the Scandinavian goddess of beauty. One year later F. Wohler established the identity of vanadium and erythro-nium. The metal itself was isolated in a reasonably pure form in 1867 by H. E. Roscoe who reduced the chloride with hydrogen, and he was...

Strangely enough, he also has a place in the history of Kthium. It was Jose Bonifacio de Andrada e Silva, who found and described the mineral petahte in a Swedish iron ore mine on the island Uto in the Stockholm archipelago, a mineral in which the element lithium was discovered. How was that possible ... 

Swedish physicist, astronomer, and spec-troscopist. He mapped the spectra of yttrium, erbium, didymium, lanthanum, scandium, thulium, and ytterbium, and in 1866 wrote a histoncal review of spectrum analysis. He also studied the magnetic properties of iron and iron ores. 

Gadolin served die University of Abo as a professor of chemistry for twenty-five years (1797-1822), and during this time he made a thorough study of tire wonderful Ytterby minerals, He also studied fluxes for decomposing iron ores for analytical purposes, made contributions to thermochemistry, helped solve the questions of chemical proportions and chemical affinity, and published the first Swedish textbook that embraced Lavoisier s views (43). 

Swedish Iron,—Notwithstanding the facilities on-joyed. in this country, and the great improvements in the manufacture of iron, still the qualities produced on different parts of. the Continent are preferred—particularly those of Sweden, Norway, and Russia—and command a higher price in the English market than the British best iron but the ores from which the Iron of these countries is made are much richer, the quantity of iron produced Is less, and the fual is of a superior kind, namely, charcoal,... 

In the Swedish deposits, the native lead-pyrochroite veins are found exclusively within or close to hausmannite and braunite ores but not in iron ore except when a manganese ore is located in the vicinity (34). In... 

About 30 years later, however, del Rio s element was discovered again. This time, the element was found by Sefstrom, who found the element in iron ore taken from a Swedish mine. He soon realized that his discovery was identical to that of del Rio s. Vanadium was eventually named for the Scandinavian goddess of love, Vanadis. 

Vanadium was discovered by the Spanish mineralogist A. M. Del Rio in Mexico in 1802/1803 (Rehder 1995), but subsequently rediscovered in 1831 by the Swedish chemist Selfstrom in smelting products from iron ores. The element was consequently named vanadium in honor of Vanadia, the northern Germanic goddess of beauty, more commonly known as Freya. The identity of vanadium was established by Wohler during the same year (Rehder 1995).

Uto is an island in the Stockholm archipelago. A silver mine was opened there in 1607 but was soon closed as the silver amount was smalL Mining of iron ore - a hematite with an iron content of 40% - had occurred in several mines since the Middle Ages and was speeded up at the beginning of the 17 century. The ore was shipped to blast furnaces on the Swedish mainland and was, to a small extent, also used in local blast furnaces, situated on neighboring islands. In the biggest and deepest mine two pegmatite veins were found. They were rich in many non-ferrous minerals, especially petalite. 

Still following the macro-structural hypothesis which we favored at that time, we abondoned the idea of a specific favorable influence of flux promoters and assumed instead that the cause for the success of the magnetite experiment was the compact porous structure of the iron sponge which was formed in the test oven by the reduction of the Swedish ore. An apparent support of this idea was that contrary to the favorable action of the dense iron sponge obtained from magnetite, catalysts of a looser structure such as, e.g., iron asbestos preparations had always been particularly ineffective. 

The title of the Swedish version of Sefstrom s new discovery actually reads Om Vanadium, en ny metall, funnen uti stdngjem, som dr tillverkadt of malm ifrdn Taberget i Smdland (On Vanadium, a new metal, found in bar iron which is manufactured from ore of the Taberg in Smaland).[ l The German pendant is entitled Ueber das Vanadin...

Cronstedt gave the name zeolite ( cco, I boil, Ldos, a stone) to a mineral species which appears to boil before the blowpipe. He described three new ores of iron, and published on gypsum, platinum, and the manufacture of lime. In his work on mineralogy, first published anonymously in Swedish in 1758, Cronstedt divided minerals into four groups earths, salts, bitumens, and metals (see p. 171), heavy spar marmor metallicum) being classed as a species ...
