其中除方铅矿外，其余矿物均存在明显产酸(Jennings et al.

Except for galena, the other minerals have obvious acid production (Jennings et al., 2000), and Mn has a strong affinity with Fe (Al-Ateeq, 2014), and often coexists with iron-bearing minerals. Oxidative acidification of sulfur minerals will accelerate the dissolution and release of these metals.

With the exception of the square lead ore, the rest of the minerals are significantly acid-producing (Jennings et al., 2000), while Mn and Fe's affinity is strong (Al-Ateeq, 2014), often coexisting with iron-containing minerals, so the oxidation of sulfur-containing minerals accelerates the interpretation of these metals.
