Barry County Lead and zinc mining in Barry County occurred primarily in the 1880s through 1890s, with some production in the 1910s, 1930s and 1940s (IMOP database). There was likely unrecorded production in the 1930s. The primary lead and zinc mining area was the Purdy mines area, located east of the town of Purdy. The mines are hosted by limestones of the Mississippian Osagean Series.

History of Lead Smelting. The process of creating lead can be traced back to 6500 Lead was created by dumping lead ore inside a furnace along with charcoal. However, it seems as though the lead was not used that often in the ancient past. The main problem was that it is too soft to be used to create a structure or forge weapons.

The smelting process involves heating the lead plates and paste to a high temperature, typically around 1,200 degrees Celsius, in a furnace. This melts the lead and separates it from other impurities, which are removed from the furnace. The resulting molten lead is then cast into ingots or other forms for further processing.
