Antimony has a negative effect on the gold extraction from antimony–gold concentrate, and it is necessary to remove antimony in advance. For a high calcium low antimony–gold concentrate (Ca–Sb–Au ore), this study proposed to pre-remove antimony using slurry electrolysis in HCl–CaCl 2 system. The results indicated that the …
Abstract Several methods have been developed to remove antimony from copper electrolytes. Previous research, however, has focussed almost exclusively on the behaviour of Sb(III), neglecting the fact that Sb(V) is also commonly found in copper electrolytes. In this project, the solubility and the ion exchange behaviour of both Sb(III) …

JASMI 168 Adsorptive Removal of Antimony (III) Using Modified Montmorillonite: A Study on Sorption Kinetics In the present work, montmorillonite (MMT, a class of Smectite clay mineral) has been selected as the host material for the removal of antimony (III) from aqueous solutions.
Antimony (Sb) is a harmful contaminant posing a risk to the environment and human health. Antimony-containing industrial wastewater often contains sulfate; therefore, it is suitable to apply sulfate-reducing bacteria (SRB) to remove Sb from such water. SRB anaerobically reduce sulfate to sulfide. Sb(V) is then reduced to Sb(III) by sulfide to …
Anjum and Datta (2012) studied the adsorptive removal of antimony (III) on modified clays at low concentration range (6 μg L − 1 -100 mg L − 1 ) and showed that montmorillonites modified with ...
The new tool developed in this study for the removal of Sb has a huge potential to treat Sb in agricultural lands. For instance, salicylic acid which plays a critical role in plant defenses is reported to reduce in the presence of Sb (Zhu et al., 2022) and this problem is common for rice farmers who produce rice in wetlands/waterlogged conditions.
Regeneration of spent accumulator acid could be an alternative process for crystallization, neutralisation and disposal. Therefore, for the first time in a study of the possibilities of electrochemical removal of antimony and accumulator acid regeneration on a laboratory scale, two synthetic and several real systems containing sulfuric acid of …
Coexisting arsenic (As) and antimony (Sb) in mining wastewater is a common and great concern. On-site simultaneous removal of As and Sb from mining wastewater was achieved by using a reusable granular TiO 2 column in this study. To evaluate the accuracy of the scale-up procedure, As and Sb adsorption from wastewater was studied …
The objective of this research was to study the precipitation of Sb and the stability of Sb2S3 during treatment of synthetic Sb(V) wastewater by sulfate-reducing bacteria (SRB). We investigated the transformation and precipitation of Sb, as well as the re-dissolution of Sb2S3 under different pH and carbon sources. The results showed that …

The exposure to Sb, either direct consumption of Sb or indirectly, may be fatal to the human health because both antimony and antimonide are toxic. Firstly, the …
Although high-efficiency antimony removal by aluminum coagulation has been expected because antimony is similar to arsenic in that both antimony and arsenic are a kind of metalloid in group V of the periodic chart, this study indicated: (1) removal density (arsenic or antimony removed per mg coagulant) for antimony by PACl was …
PMID: 38141916. DOI: 10.1016/j.envres.2023.118011. Microbes have been confirmed to play key role in biogeochemistry of antimony. However, the impact of indigenous bacteria (from active mines) on the behavior of dissolved antimony remained poorly understood. In current study, the hyper antimony-resistant strain, Achromobacter sp. 25-M, from the ...
Antimony (Sb), a global and priority controlled pollutant, causes severe environmental issues. Bioremediation by microbial communities containing sulfate-reducing bacteria (SRB) is considered to be among the safest, economical, and environmentally friendly methods to remove Sb from wastewater. However, the roles of SRB species in …

However, antimony has high cumulative toxicity and carcinogenicity in humans [3,4]. Therefore, to protect human health, many countries and organizations have listed antimony as a priority pollutant [5].
