Epsom Salts Monorail Epsom Salts Monorail The Epsom Salts Monorail or Magnesium Monorail was a short-lived Lartigue Monorail in San Bernardino County, California, in the United States. It was built to carry epsomite (hydrated magnesium sulphate) from a deposit in the Owlshead Mountains to a siding of the Trona Railway. It ran nearly due east from Trona, for a distance of about . The monorail was opened in 1924 and closed in June 1926. Thomas Wright, a florist from Los Angeles, set-up a camp in Crystal Hills Wash in 1918 and prepared an area for salt mining, where he had previously found some
Magnesium chloride made from solar evaporation of seawater. Anhydrous magnesium chloride is the principal precursor to magnesium metal, which is produced on a large scale. Hydrated magnesium chloride is the form most readily available. MgCl crystallizes in the cadmium chloride motif, which features octahedral Mg centers. Several hydrates are known with the formula MgCl(HO), and each loses water at higher temperatures: x = 12 (−16.4 °C), 8 (−3.4 °C), 6 (116.7 °C), 4 (181 °C), 2 (about 300 °C). In the hexahydrate, the Mg is also octahedral, but is coordinated to six water ligands. The thermal dehydration of the hydrates MgCl(HO) (x
