What is the main mining product of Connecticut?

Answer 1

There is nothing seriously mined in Connecticut. Connecticut used to produce barite (copper ore) but all such mines have been exhausted and mostly abandoned. There is a limited amount of specialty stone produced, notably Portland brownstone. Connecticut has at least three large successful gravel pits, producing everything from trap rock to decorative pea stone. Both garnets and gold have been found in the state, but in quantities far too small to be commercially viable. There are few of small deposits of very poor quality coal, but don't amount to large enough to be mined.
