Wulfenite

Wulfenite

This is an eye catching mineral sample purchased from Don Smoley last June.

Wulfenite

It is mounted on a short matchstick.  According to Wikipedia, it is a lead molybdate mineral.  I read it can be orange, yellow, red-orange, yellow-orange or brown.

  Molybdenum can be extracted from Wulfenite.  Molybdenum was the component needed in the metal of jet engine compressor blades to increase their service life.  Back in the day, 1945, they would have to rebuild the engine after 25 hours of running.

This sample comes from Rowley Mine, Maricopa Co., Arizona.  Somewhere, I have a sample from a mine in Mexico.  I will show it if I find it.
