The Federal No. 3 Mill (right) was the largest concentrator operated by the St. Joseph Lead Company in the Old Lead Belt.

Run-of-mine ore passed through primary and secondary crushers before ascending to the top of the mill by twin conveyors. | 
Close-up view of the shaft headframe. An extensive system of underground rail lines linked the mill to mines. The power house building (at the extreme right edge of the photo) contains a mining museum.

| PALMER MINING DISTRICT

| (Left and above) The MHAers brave the underbrush to reach the remains of an 1836 Scotch hearth lead furnace.
The Palmer Mining District, in Washington County, is one of the oldest in the state of Missouri. It operated on a plantation system where land was owned by the mining company and both the employees and contract miners worked the shallow galena deposits by hand. The ore was delivered to the central furnace. |
