Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …

Antimony is a strategic metal which is used in many industrial areas. The content of the antimony ore is the most important point for determining the area of usage. Since, high-grade antimony ores ...
Antimony is a chalcophile, occurring with sulfur and the heavy metals copper, lead and silver. More than 100 minerals of antimony are found in nature. Some of the more common ones, as summarized by the author, are listed in Table 1. Industrially, stibnite (Sb 2 S 3) is the predominant ore of interest and importance. Stibnite deposits are ...
Antimony features highly on the critical minerals lists of many countries including Australia 3, the United States of America 4, Canada 5, Japan 6 and the European Union 7. Critical minerals are those minerals (or elements) considered vital for the well-being of the world's economies, yet whose supply may be at risk of disruption. JORC Ore …
Tetrahedrite ore is a complex sulfide and one of the most common sulfosalt minerals containing strategic elements such as antimony, arsenic, and copper.
