Iron mining in the United States began in 1608, when a ship returning from the Jamestown Colony in Virginia carried a load of iron ore back to England. The manufacturing of iron from ore likely began in 1622, in what is now Chesterfield County, Virginia, but was halted when American Indians killed everyone in the establishment.
