    The US has two smelter facilities, one primary and one secondary, producing commercial-grade zinc metal. Primary smelters produce metal from ore. The only US primary zinc smelter, the Nyrstar smelter at Clarksville, Tennessee, produced 120 tonnes of zinc, from a mix of ore from six mines in middle and east Tennessee, and recycled zinc products.
