Lead Losses: In Tailings: The lead losses in the tailing varied from 0.12 to 0.47%. Most of the sulphide lead in the tailing was in the form of locked particles, that is, small grains of galena attached to other sulphides or gangue minerals. Finer crushing and froth flotation would enable recovery of most of this lead.

Respectively, galena (PbS) and chalcopyrite (CuFeS 2) are the main raw materials for extracting metallic lead and copper, and these two minerals are often present in deposits as polymetallic sulfide ores in the form of symbiotic or associated minerals (Liu et al., 2020, Patra and Natarajan, 2008). Currently, flotation technology (Huang et al ...

It is lead sulfide (PbS). When pure, it contains 86.6% lead and 13.4% sulfur. Galena is metallic lead gray with a bright metallic luster when freshly broken, and dark gray to black when weathered. It is brittle and very heavy (about 7.6 times as heavy as water). Galena most commonly forms cubic crystals, and breaks with perfect cubic cleavage.

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 …
