Dajiagou Creek (Banpo mine)
Guizhou, Dushan County, Banpo mine, China
Rivers and surface water
- Type
- River or surface water
Banpo antimony mine (Guizhou): 26 waters sampled in the Dajiagou Creek, which crosses the waste heaps, in the Chahe River, which receives the processing tailings, and in the Qisha tributary; Sb up to 1427 µg/L and sulfate up to 1926 mg/L. Dissolved sulfate δ34S follows Sb and sulfate in the Chahe (r = 0.68 and 0.89): a tracer of the pollution extent; isotope budget: about 59 % of the sulfur of the lower Chahe comes from the mine (Ning et al., 2011). The creek turns acidic below the waste heaps (pH down to 3.6); its sulfate carries the stibnite signature (+5.19 ‰), i.e. 97 % mine sulfur. Coordinates not published (map only).
