Who / whereby / as soon as / HowDiscoverer: known to pre-Columbian south Americans. Taken to Europe about 1750Discovery Location: south AmericaDiscovery Year: UnknownName Origin:Spanish: platina (little silver).Abundance the Platinum:Earth"s Crust/p.p.m.: 0.001Seawater/p.p.m.: Atlantic Suface: N/AAtlantic Deep: N/APacific Surface: 1.1E-07Pacific Deep: 2.7E-07Atmosphere/p.p.m.: N/ASun (Relative come H=1E12): 56.2Sources the Platinum:Produced native platinum ore or aboriginal platinum deposits. Primary mining areas are Urals in Russia, Canada, south Africa Columbia and also Peru. Yearly world wide production is approximately 30 tons.Uses the Platinum:Used in jewelry, to do crucibles, distinct containers, together a catalyst, in dental crowns, together an anti-tumor agent and to make traditional weights and measures. The is likewise combined with cobalt to produce very solid magnets.Additional Notes:Some sources attribute the exploration of platinum to Antonio de Ulloa the Spain in 1735 or timber in 1741, however, it had actually been well-known to and also used through the pre-Columbian ind in southern America long before that time. Therefore we have opted to credit transaction the an initial users of platinum with the discovery, not the european explorers/scientists the "rediscovered" it and brought it to Europe.
