Antimony, as a new global pollutant, is one of the most concerned toxic metal elements in the world. Antimony is widely applied in the manufacture of various flame retardants, glass, pigments, ceramics, medicine and chemical industry (Filella et al., 2002). Because of its extensive applications, a large number of antimony containing pollutants are discharged into …
Antimony use is widespread in the world and workers need to be completely protected by being provided with overalls and respirators, with regular monitoring of air levels and inspection of air extraction systems. Its biological monitoring in the workplace is essential. One interesting study suggested sweat excretion studies of antimony.
Six extraction media (acetic acid, EDTA, tetrabutylammonium hydroxide, NaOH, MeOH/H2O, acetonitrile/H2O) were tested for their ability to extract antimony (Sb) and arsenic (As) from freeze-dried poplar leaves, pine shoots and spruce shoots, as well as from a peat matrix. Additionally, the extraction …
Alongside its antimony recycling, Campine has also been expanding its extraction of other metals such as tin, silver and gold from industrial waste streams. In May 2018, the company announced its intention to invest up to €25 million ($30 million) in recycling projects, with the largest single amount going into recycling the plastic housing of batteries.

This work proposes a novel environmentally-friendly, low temperature phase-conversion method for antimony extraction and studies its experimental application and feasibility in pyrite cinder waste co-treatment. The detailed phase transformations and microstructural evolution mechanisms during antimony extraction and sulfur fixation process were investigated.
The SE selectively leached antimony, while gold and arsenic were retained in the residue as a raw material for further gold extraction. The antimony content in the cathode antimony was >98%, and arsenic content was less than or equal to 0.21%. The As-Au-Sb ore consisted of stibnite (Sb2S3), pyrite (FeS2), arsenopyrite (FeAsS), and quartz (SiO2), along with a small …
The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.
Total antimony extraction in grape juice samples. The extraction of total antimony from grape juice samples was studied and optimized according to some works found in the literature for different matrices (Elhadri et al., 2007, Petit de Peña et al., 2001, Rondón et al., 1995). Three different acids (HCl, HNO 3, and H 2 SO 4) at different concentration levels (three independent …
Antimony extraction from e-waste plastics was more challenging: aqua regia was ine cient for poly (acrylonitrile butadiene styrene) (ABS) samples (extraction yield was about 20% only), while on a mixture of ABS and polycarbonate (PC), aqua regia, H2SO4 and HCl exhibited equivalent performances (~21%). Ashed samples returned yields ranging from 20% to over 50%. Room …

Antimony can be separated from antimonite through two processes. In the first process, antimonite is reacted with pure iron on a one to three basis; the result of the reaction forms pure antimony and iron sulfide. The second separation process of antimony uses charcoal to extract antimony from the hydrogen sulfide.
