The district, which extends into southwestern Missouri, northeastern Oklahoma, and the very southeastern corner of Kansas, was once one of the major lead and zinc mining areas in the world. From 1850 to 1950, the district produced 50 percent of the zinc and 10 percent of the lead in the United States, with production peaking between 1918 and 1941.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

4. Electrolysis. In the electrolysis department, the zinc contained in the solution is deposited onto aluminum cathodes in a process called electrowinning. This happens by passing an electric current through cathodes and anodes. The cathodes are removed from the cells and the zinc sheets are stripped from the cathodes and sent to casting.
