Is galena valuable? Is it hard to find in nature?

Galena is commonly found in areas of limestone or dolomite rock. These rocks formed in tropical shallow oceans. Openings, called vugs, can become filled with new minerals like pyrite, marcasite, or galena over time. Galena (PbS, lead sulfide) is mostly found in the driftless areas of Missouri, Illinois, Kansas, Oklahoma, Iowa, and Wisconsin or in Colorado, Idaho, Montana, and Utah. Galena is mined as a lead ore and many times is associated with zinc, copper, and silver. It is a valuable commodity, adding over a million dollars to the state of Missouri's income each year.
