The U.S. Government has considered antimony to be a critical mineral mainly because of its use in military applications. The great majority of the world's antimony comes from China, and much of the remainder is shipped to China for smelting. Antimony resources are unevenly distributed around the world.
Antimony mining has resulted in considerable pollution to the soil environment. Although studies on antinomy contamination have been conducted, its effects on vertical soil profiles and depth-resolved microbial communities remain unknown. The current study selected three vertical soil profiles (0-2 …

When the antimony smelting slag contains Pb ~1.2%, Zn ~6.9%, and Sb ~1.4%, the metal recovery of Pb, Zn, and Sb after fuming and volatile process will be 95%, 88%, and 60%, respectively. Meanwhile, the coal consumption is ~0.3 t per ton antimony smelting slag, when the pulverized coal with 59.92% fixed carbon is utilized as reductant and fuel.
The smelting process of antimony is roughly classified into dry process and wet process, and the former is currently applied. Volatilize roasting-reduction method is applied for poor ore, and iron precipitation method is used for rich ore processing.

How much antimony is lethal? The lethal oral dose of metallic antimony in rats is 100 mg/kg of body weight; the trivalent and pentavalent oxides are less toxic, with LD50 in rats ranging from 3200-4000 mg/kg of body weight. The recommended workplace limit (ACGIH TLV-TWA) for antimony is 0.5 mg/m3 as an 8-hour time-weighted average.
