Zgodovina
Artifacts made from metallic meteorites have been found dating from as early as 5000 BC.
In 1751, Baron Axel Fredrik Cronstedt was trying to extract copper from kupfernickel and instead produced the white metal.
In the early twentieth century, Ludwig Mond patented a process using nickel carbonyl to purify nickel.
