Antimony: A Mineral with a Critical Role in the Green Future

If someone asked you to name the first mineral that came to mind, odds are, it wouldn’t be antimony.

Yet, despite its lack of fanfare, it plays a significant role in our day-to-day lives. This graphic from Perpetua Resources provides an overview of antimony’s key uses, and the critical role it plays in the movement towards clean energy, among other uses.

What even is Antimony?

Antimony is an element found in the earth’s crust. Rarely found in its native metallic form, it is primarily extracted from the sulfide mineral stibnite.

It has a variety of uses and is found in everything from household items to military-grade equipment. Because it conducts heat poorly, it’s used as a flame retardant in industrial uniforms, equipment, and even children’s clothing.

Its second most common use, according to USGS, is in transportation and batteries. Traditionally, antimony has been combined with lead to create a strong, corrosion-resistant metal alloy, which is particularly useful in lead-acid batteries.

However, recent innovation has found a new use for antimony—it now plays an essential role in large-scale renewable energy storage, which is critical to the clean energy movement.
