GMS - Pyrite - Georgia Mineral Society

Originally, the mines were opened to extract copper and iron. Eventually, copper became too expensive to mine there, so the real value of the pyrite was realized. Pyrite was mined there and processed into sulfur and sulfuric acid until 1987. But, it's the different "looks" of pyrite that captivate me. Just remember, strange.
