History

C.W. Scheele discovered molybdenum in 1778 in a substance that he called molybdic acid. P.H. Hjelm isolated it as an element in 1790. Between two-thirds and three-fourths of the world supply of molybdenum comes from mines where its recovery is the primary objective of the operation. The remainder is recovered as a by-product of certain copper mining operations, largely in the United States and Chile.
