Ores of nickel are mined in over 23 countries and are smelted or refined in 25 countries. ... Primary nickel is produced and used in the form of ferro-nickel, nickel oxides and other chemicals, and as more or less pure nickel metal.]]> 2018-02-28 13:22:13 UTC https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236363894 cortesjimenez_j https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236367502 It is extensively used for making stainless steel and other corrosion-resistant alloys such as Invar(R), Monel(R), Inconel(R), and the Hastelloys(R). Tubing made of copper-nickel alloy is extensively used in making desalination plants for converting sea water into fresh water.]]> 2018-02-28 13:30:25 UTC https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236367502 cortesjimenez_j https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236368747 Nickel was discovered by the Swedish chemist Axel Fredrik Cronstedt in the mineral niccolite (NiAs) in 1751. Today, most nickel is obtained from the mineral pentlandite (NiS. 2FeS). Most of the world's supply of nickel is mined in the Sudbury region of Ontario, Canada.]]> 2018-02-28 13:33:12 UTC https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236368747 cortesjimenez_j https://padlet.com/cortesjimenez_j/pauuoklfcwy1/wish/236370034 Ni Melting point 1453° C
