The Zijiang River (referred to as "ZR") is an important tributary of the Dongting Lake Basin in the midstream region of the Yangtze River. The ZR Basin is located in the ultra-large Sb ore belt, and various Sb ores have been confirmed in the basin, for example, the world's largest Sb mine, Xikuangshan, is in this region (Liu et al., 2023).Due to hundreds of years of …
