Zinc processing Zinc processing Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world''s output originates in North America and Australia. The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or ...
Zinc ore was discovered with increasing frequency near the bottoms of old lead mines. The Mineral Point Zinc Company was founded in 1882, and by 1891 it was operating the largest zinc oxide works in the United States at Mineral Point. Zinc mining and processing continued on a large scale until the 1920s.
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 .
