Antimony as a global dilemma: Geochemistry, mobility,

2017-4-1  Antimony and natural Sb-bearing sulfides were found as early as 4000 BCE. Up to date, a variety of industrial operations such as production of paint pigments, flame retardants, plastics, glassware and ceramics, and alloys in ammunition and battery manufacturing plants extensively utilize Sb; as a result the global consumption of Sb has increased to more than 1.4 × 10 5 tons each year (Guo et ...

Antimony uptake by mangroves and its environmental fate

2021-1-5  Antimony (Sb), a naturally occurring trace element, tends to be enriched in the top-soil and contributes to soil contamination due to continued human activities. However, little is known about plant uptake of Sb, its storage in plant biomass and recycling in large littoral zones of tropical regions, subjected to strong anthropogenic impact.

Antimony - Perpetua Resources

Antimony and the Green Economy . Numerous studies are showing antimony will be key to helping us achieve a more sustainable and efficient future. It can be used in molten-salt batteries, solid-state batteries, semi-conductors, and even self-healing solar panels.. Researchers at MIT have developed an antimony based liquid battery that will allow for the large-scale storage of renewable energy.
