Feishuiyan stream (Xikuangshan mine)
Hunan, Xikuangshan district (Lengshuijiang), China
Rivers and surface water
- Type
- River or surface water
Xikuangshan antimony mine (Hunan), the world's largest: waters of the Feishuiyan stream, aquifer springs and wells and Shetianqiao adits, all alkaline (pH 6.8 to 8.9) and very Sb-rich (up to 47 mg/L). δ123Sb of -0.20 to +0.73 ‰ (Spex lot CL8-06SBY): oxidative weathering of stibnite, waste heaps and slags, adsorption onto Fe-Mn oxyhydroxides and mixing (Wen et al., 2023). Coordinates not published. The mining stream has a stable δ123Sb (+0.19 to +0.24 ‰, excluding R5), despite inputs of mine and spring waters; tributary R5, influenced by slags, is heavier.
