Antimony process - American, Smelting Refining
The process according to claim 1 in which the high copper dross is fumed to yield antimony oxide, an antimony slag and residual metal. 3. A process according to claim 1 in which the metal after separation of the high copper dross is further cooled to yield a dross relatively high in antimony which is returned to the fuming furnace and a residual metal suitable for return to the softening operation.
The exposure to and health effects of antimony
Antimony may enter the environment as a consequence of mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations with other substances. Antimony released from smelters may remain in particulate quantities in the air, some of which reaches the soil during rainfall where it attaches strongly to particles containing iron, manganese, or …

Antimony Trioxide - an overview | ScienceDirect Topics
The precise mechanisms of antimony carcinogenicity remain unknown; however, due to its electrophilicity antimony has a high affinity for DNA and protein thiol groups. Antimony has been shown to impair the nucleotide excision repair, nonhomologous end-joining repair, and homologous recombination DNA repair pathways in vitro [155, 156].
antimony | Definition, Symbol, Uses, & Facts | Britannica
Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite.

occurs as either a distinct antimony bearing sulfide, such as stibnite, sulfosalt minerals, such as. tetrahedrite, rare antimonides, such as aurostibite, or as minor or trace constituent in sulfides such. as arsenopyrite and pyrite. More than 100 minerals of antimony are found in nature.
Historical Uses of Antimony Metals
In 1784, British General Henry Shrapnel developed a lead alloy containing 10-13 percent antimony that could be formed into spherical bullets and used in artillery shells in 1784. As a result of the British militarys adoption of Shrapnels technology in the 19th century, antimony became a strategic war metal.
