- When I had free time, I used to be an amateur mineralogist and
- still have some books on the subject. According to a couple
- of them, molybdenum was, and probably still is, used to make
- highly durable steel for high speed tools of many kinds. It
- was also mixed with chrome and other metals for other types
- of steel, including rocket tubes. Nothing lasts forever.
- Any place that has tools wearing out or metals being recycled
- could potentially leach amounts into the environment.
- Molybdenite also occurs as an ore, close to the surface near
- several rivers--including the Consumnas river in northern
- California, near the old civil war era copper mine.
