Embodiment 1
[0031] For a lead-zinc tailings mine, the sulfur content in the ore is 15.87%, and the iron content is 27.93%. The metal minerals in the ore are mainly pyrrhotite and pyrite. Pyrrhotite accounts for 21.84% of the total mineral content, pyrite accounts for 9.62% of the mineral content, and magnetite mineral content is 2.16%. In addition to these useful minerals composed of beneficial elements, there are also a large number of veins in the ore. Stone minerals feldspar, pyroxene, diopside, garnet, quartz and other silicate rocks, and also contain a small amount of other gangue minerals such as calcite.
