What is Antimony?

Antimony (Sb) is a strategically important mineral that plays a key role in a range of industrial applications, from electronics to defence and renewable energy. Classified as a critical mineral by governments around the world, including Australia, the United States, the European Union, and Japan, antimony’s significance is increasing as the global demand for high-tech and green energy solutions grows.

Antimony is a metalloid known for its versatility and unique properties, which make it a valuable component in various manufacturing processes. It is primarily used in flame retardants, lead-acid batteries, and semi-conductors, as well as in solar panels, glass manufacturing, and military technologies like missile guidance systems, night vision equipment, and nuclear weapons, making it vital for national security. The metal’s ability to resist heat and corrosion, combined with its conductive properties, makes it indispensable in both traditional industries and emerging technologies.

Antimony is recognised as a critical mineral due to its essential role in national security and industrial processes, as well as the concentrated nature of its global supply. China dominates antimony production, accounting for nearly 50% of the world’s supply, but recent export restrictions have disrupted the market, driving up prices. This has created an urgent need for alternative sources of antimony, positioning countries like Australia as potential key suppliers.

The growing focus on sustainable energy and advanced technologies is boosting antimony’s relevance in modern industries. One of its most promising applications is as an anode material in lithium-ion batteries, where it helps improve energy storage efficiency, a key factor in the global shift towards electric vehicles and renewable energy systems.

Antimony is also vital in the production of photovoltaic cells used in solar panels, where it enhances the efficiency of converting sunlight into electricity. As governments worldwide push for a green energy transition, the demand for antimony in solar technologies is expected to accelerate. As global recognition of antimony’s value increases, the market is expected to expand, reinforcing its status as a critical commodity for emerging technologies and essential industrial applications.

Recognising the critical importance of antimony, Trigg Minerals has strategically positioned itself to meet the growing demand for this essential mineral. With the Achilles Antimony Project—home to Australia’s highest-grade undeveloped antimony deposit at Wild Cattle Creek—and the Taylors Arm and Spartan Antimony Projects, Trigg is well-placed to be a significant player in the global antimony market.
