The pH-dependent leaching of antimony (Sb) and arsenic (As) from three typical Sb-bearing ores (Banxi, Muli and Tongkeng Antimony Mine) in China was assessed using a pH-static leaching experiment. The pH changes of the leached solutions and pH-dependent leaching of Sb and As occurred in different ways. For the Banxi and Muli Sb …Web

Antimony (Sb) is ubiquitous throughout the environment as a result of natural processes and human activities. In China, superlarge-, large and medium-sized Sb deposits are concentrated in the Guangxi (34.4%), Hunan (21.2%), Yunnan (12.2%) and Guizhou (10.2%) provinces. Due to Sb mining and smelting processes, large quantities of Sb …Web

One reason is that antimony is far less valued than other key metals (such as lithium, cobalt, nickel, and rare Earth) before it is widely used in clean energy. Another reason is that China has been the world's Antimony mining center for decades, accounting for more than half of the world's antimony production during the research period.Web
