critical metals [9]. The processing of antimony ores and the production of antimony metal is also concentrated in China, due to its high smelting capacity. Most of the antimony industry in Europe and the U.S.A. is therefore dependent on the import of Chinese antimony metal and is focused on the production of high-purity products and applications.
Moreover, China's antimony ore mining accounted for 52% of the world's antimony mining in 2020, with extraction of antimony ores also ranking first in the world . With the increasing development of mining technology, the production process of antimony mineral resources, mainly jamesonite and stibnite, has become increasingly mature.
