Iron and copper ores frequently contain molybdenum, sometimes in quantity; consequently it is met with in slags and pig-iron.

All molybdenum compounds are converted into the trioxide by boiling with nitric acid.

Vanadium is white, and when its surface is polished, it resembles silver or molybdenum more than any other metal.

We noted a similar close resemblance between the positive strontium and the negative molybdenum.

It consumes a lot in its own steel industry, even using manganese as a substitute for scarcer alloys like nickel and molybdenum.
