Söyüdlü (also, Segyutlyu, Sëyudlyu, Sogyutlu, and Sogyutlyu) is a village and municipality in the Gadabay Rayon of Azerbaijan. It has a population of 2,372.
The nearby Gadabay gold mine, in use since 2012, is operated by the British company Anglo Asian Mining. A six million cubic metre tailings pond for the mine, containing arsenic and cyanide, was placed a few hundred metres from Söyüdlü. Residents of the village have said that the toxic waste is poisoning them and their crops. Following protests of the planned installation of a second tailings pond in June 2023, the operation of the mine was temporarily suspended.[1] [2]
