Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony's leading use is as a fire retardant in safety equipment and in goods, such as mattresses.
Antimony is an incompatible chalcophile element. ... isotope analyses allowed to assess the potential of δ123Sb NIST3102a as a proxy for ore forming [1] and oxidation/weathering [2] processes. Application of this proxy, however, is limited by the lack of knowledge of the Sb isotope composition of the Earth and its fractionation during high ...
