Mercuryville, California become a ghost town. One of the last remaining large mine buildings was burned in wildfires in the mid-1970s, although some concrete structures and metalwork from the mines remain. Mercuryville, California Mercuryville, California is a ghost town in the Mayacamas Mountains along The Geysers road. Mercuryville was founded in 1874, after cinnabar, a mercury bearing ore, was discovered in eastern Sonoma County around 1870. Mercury is a dense liquid metal that can be used to separate gold from other less dense materials and the California Gold Rush, which had begun only 20 years earlier, increased the demand and price of
Metal ammine complex is ammonia (pK ~ 33). For highly cationic complexes such as [Pt(NH)], the conjugate base can be obtained. The deprotonation of cobalt(III) ammine-halide complexes, e.g. [CoCl(NH)] labilises the Co-Cl bond, according to the Sn1CB mechanism. Metal ammine complexes find many uses. Cisplatin (PtCl(NH)) is a coordination compound containing two chloro and two ammine ligands. This is a drug used in treating cancer. Many other amine complexes of the platinum group metals have been evaluated for this application. In the separation of the individual platinum metals from their ore, several schemes rely on the precipitation of [RhCl(NH)]Cl. In some separation schemes,
