Basic Information On Molybdenum

In 1782, Elm of Sweden obtained molybdenum by burning a mixture of charcoal and molybdic acid mixed with linseed oil in a closed chamber [2].
In 1953, molybdenum was recognized as an essential trace element for humans, plants and animals.
The main mineral is molybdenite (MoS2).

Natural molybdenite MoS2 is a soft black mineral, similar in appearance to graphite, and both were sold in Europe under the name "molybdenite" until the end of the 18th century, when in 1779 Scheele pointed out that graphite and molybdenite were two completely different substances. He found that nitric acid had no effect on graphite, but reacted with molybdenite to obtain a chalky white powder, which, when boiled with an alkaline solution, crystallized into a salt. He considered this white powder to be a metal oxide, and mixed it with charcoal and strongly heated it, obtaining no metal, but the original pyromolybdenite after co-heating with sulphur.
In 1782, Elm, a Swedish mine owner, isolated the metal molybdenum from molybdenite, naming it molybdenum, with the elemental symbol designated as Mo. The Chinese translation is molybdenum. It was recognized by Betsy Rius and others.
