Sur le plan environnemental, l'antimoine pollue l'atmosphère par le biais de poussières et de gaz toxiques, les eaux naturelles par le biais de formes solubles et les sols par accumulation lente. La majeure partie de l'antimoine est commercialisée sous forme …
Abstract: The extraction of antimony and arsenic from galena concentrates by leaching with strongly alkaline sodium sulphide solution are investigated. The effects …
These techniques lead to a strong concentration of the antimony, which can then be used as a source of antimony, when renewing or regenerating the sorbent or …
A new pyrometallurgical process to extract antimony from stibnite concentrate was proposed. Thermodynamic analysis of extraction process was …
In this study, a complete technological process for extracting antimony from refractory gold ore was proposed, which included leaching, pressure oxidation, …
Homogenization is the first step for most non-liquid samples, frequently followed by protein precipitation or saponification. The dominant extraction techniques …
The technique consisted of two steps of addition of a metal (manganese, aluminum or a combination of both) in 1–5% of the total weight of antimony followed by …

On décrit trois techniques d'extraction simples, utilisant l'éther isopropylique, l'hexone et le tributylphosphate, pour la séparation du radioantimoine des radio-nucléides gênants. …
L'extraction de l'antimoine à partir de solutions chlorhydriques dans des mélanges méthanol, éthanol et acétone-eau est plus élevée qu'a partir de solutions aqueuses …
