Strontian is the main village in Sunart, an area in western Lochaber, Highland, Scotland, on the A861 road. It lies on the north shore of Loch Sunart, close to the head of the loch. In the hills to the north of Strontian lead was mined in the 18th century and in these mines the mineral strontianite was discovered, from which the element strontium was first isolated.
The village name in Gaelic, Sròn an t-Sithein, translates as the nose [i.e. 'point'] of the fairy hill, meaning a knoll or low round hill inhabited by the mythological sídhe. The nearby hamlets of Anaheilt, Bellsgrove, and Upper and Lower Scotstown are now generally considered part of Strontian, with Polloch several miles away on the terminus of the road to Loch Shiel. Strontian is the location of Ardnamurchan High School, the local fire station, police station and other facilities.
The history of mining in the Strontian area dates to 1722, when Sir Alexander Murray discovered galena in the hills the region. A mine was opened in 1725, in partnership with Thomas Howard, 8th Duke of Norfolk and General Wade. Various materials have been mined here including lead, and strontianite, which contains the element named after the village, Strontium. While there have been inhabitants of the area for centuries, particularly in the woods north of the current village, the community as it exists now was established in 1724 to provide homes for the local mining workers.
Is was observed in the 19th century that there is granite on one side of the Strontian mines and gneiss on the other. The glen north of the village is situated within the Moine Supergroup. The Glenfinnan Group lies on the west side of the glen, with Caledonian intrusions on the east side.
Lead mined at Strontian was used in bullets manufactured for the Napoleonic Wars. In the early part of the 19th century, part of the workforce was made up of captured forces from Napoleon's imperial army.
In 1790, Adair Crawford, a physician, recognised that the Strontian ores exhibited different properties to those normally seen with other "heavy spars" sources. He concluded "... it is probable indeed, that the scotch mineral is a new species of earth which has not hitherto been sufficiently examined". The new mineral was named strontites in 1793 by Thomas Charles Hope, a professor of chemistry at the University of Glasgow. He confirmed the earlier work of Crawford and recounted: "... Considering it a peculiar earth I thought it necessary to give it an name. I have called it Strontites, from the place it was found; a mode of derivation in my opinion, fully as proper as any quality it may possess, which is the present fashion". The element was eventually isolated by Sir Humphry Davy in 1808 by the electrolysis of a mixture containing strontium chloride and mercuric oxide, and announced by him in a lecture to the Royal Society on 30 June 1808. In keeping with the naming of the other alkaline earths, he changed the name to strontium.
The first large scale application of strontium was in the production of sugar from sugar beet. Although a crystallisation process using strontium hydroxide was patented by Augustin-Pierre Dubrunfaut in 1849 the large scale introduction came with the improvement of the process in the early 1870s. The German sugar industry used the process well into the 19th century. Prior to World War I the beet sugar industry used 100,000 to 150,000 tons of strontium hydroxide for this process per year.
