Keywords: antimony; Sb; arsenic; As; extraction; galena; sodium sulphide; leaching 1. Introduction Antimony is a metal with strategic importance and a wide range of applications. The research about antimony extraction is significant due to the fact that it is rarely found in nature alone, but mostly in association with other metals [1].

This study aims to evaluate the performance of different leaching schemes with respect to the mobilization of antimony and arsenic from polluted samples collected at different sites in Mansfeld District, Germany. Besides the elution by water the leaching by artificial acidic rain and by two different schemes of sequential extraction were …

Tetrahedrite conventional leaching process is strongly chemical-dependent process which needs high temperature values for optimum extraction of antimony. …

Arsenic-containing antimony gold concentrate (As-Sb-Au ore) is an important raw material for antimony and gold extraction [1–3]. Antimony often exists in the form of stibnite and usually needs to be removed before gold extraction [4–7]. Zhang et al. [8] proposed a slurry electrolysis (SE) method to pretreat this As-Sb-Au ore.

Abstract. Antimony has been listed as a critical pollutant in many countries because of its toxic effects on earth organisms. In this study, titanate nanosheets (TNS) …

A new sequential extraction procedure was proposed and applied to the fractionation and redox speciation of antimony in agricultural soils, using EDTA + ascorbic acid, pH 7 (available under complexing and moderately reducible conditions); oxalic acid/oxalate + as Corbenic acid (extractable in reducible Conditions) and HNO3 + HCl + HF (residual ...

In this work, a new polymeric ionic liquid (PIL)-based sorbent was prepared by in-situ polymerization of 3-(1-ethyl imidazolium-3-yl) propyl-methacrylamido bromide and ethylene dimethacrylate and was used as medium for stir cake sorptive extraction (SCSE) of trace antimony in environmental water samples. The sorbent EPBED was …

Antimony (Sb) - Occurrence, Extraction, Properties and Applications. Antimony was (Sb) not known when antimony was first discovered, although it was known to exist in compounds by ancient civilisations. It was known to exist is metallic form in the 17th century and possibly even earlier. Antimony and several of its compounds are …

The reaction mechanism is explained with the fact that various antimony species predominate in the solution at various chloride ion concentrations. At acidities below 0.5 M, antimony extraction coefficient is a second order function of the acidity, while at acidities above 0.5 M, antimony extraction coefficient is independent of the acidity.

We report on a simple, sensitive and reliable method for the cloud point extraction of antimony (Sb) and its subsequent spectrophotometric detection. It is based on the color reaction of Sb (III) with iodide in acidic medium and subsequent micelle-mediated extraction of tetraiodoantimonate using a non-ionic surfactant in the absence …
