Mine[edit] Quartz
Quartz
was mined in the area beginning in the 1500s for the ironworks in Uppland. Feldspar
Feldspar
was mined for local porcelain manufacture, such as Gustavsberg, and the porcelain trade with Britain and Poland.[2] The mine is likely the first feldspar mine in Sweden, starting in 1790. Feldspar
Feldspar
mining was likely sporadic, and based on manufactures demand. This demand took off in the 1860s, leading to deeper mining efforts at Ytterby. The mine became one of the most productive quartz and feldspar mines in the country.[3] Feldspar
Feldspar
and quartz mining continued until 1933 when the mine was shut down. With 177 years of feldspar mining, it was the longest mined feldspar mine in Sweden. Towards the end of the 1940s, the Swedish state, through the REF (Riksnämnden för ekonomisk försvarsberedskap) became interested in possible usage of the mine. In 1953, the mine was renovated and used for the storage of jet fuel - MC 77. The storage method led to contamination of the jet fuel, leading to problems in jet engines that used the fuel. The storage of jet fuel ended in 1978. It was subsequently used to store diesel. In 1995, the mine was completely emptied, and in the following years the area began rehabilitation.[3] Chemical discoveries[edit] The mine's elemental history began in 1787, when Lieutenant Carl Axel Arrhenius found an unidentified black mineral. He had previously explored the area for a potential fortification.[3] His hobby interest in chemistry led him to notice the unusually heavy black rock, which he and friend Bengt Geijer examined with Sven Rinman. It was not until Finnish chemist Johan Gadolin
Johan Gadolin
fully analysed the mineral in 1794 and found that it 38% of its composition was a new, unidentified earth element. Swedish chemist Andres Gustaf Ekeberg confirmed the discovery the following year, and named it yttria, with the mineral named gadolinite.[4] Many rare earth elements were discovered in the mineral gadolinite, which eventually proved to be the source of seven new elements that were named after the mineral ore and the area. These elements include yttrium (Y), erbium (Er), terbium (Tb), and ytterbium (Yb)[1] and were first described in 1794, 1842, 1842, and 1878, respectively. In 1989 the ASM International society installed a plaque at the former entrance to the mine, commemorating the mine as a historical landmark.[5] In addition, three other lanthanides, holmium (Ho, named after Stockholm), thulium (Tm, named after Thule, a mythic analog of Scandinavia), and gadolinium (Gd, after the chemist Johan Gadolin) can trace their discovery to the same quarry[6] making it the location with most elements named after it.
