    Lead and zinc mining GeoKansas

    The lead was extracted from the mineral galena, and the zinc was extracted from the mineral sphalerite. In general, mining was done underground, using the room-and-pillar method, in which room-shaped areas were mined and large pillars of rock left in place for roof support. Underground rooms had walls 25 to 100 feet high and pillars 20 to 50 feet thick. In areas around the town of Galena, where the ore was
