Nowadays, molybdenum is routinely used to harden structural and tool steel, and to reduce corrosion.Additional articles that might interest you...

Throw-Away Gold: Back to Basics
February 2002
Placer mining, whether for profit or recreational purposes, involves separation of free gold from the gold-bearing sands (gangue) of alluvial deposits by methods using specific gravity.
