Environmental mobility of antimony around mesothermal stibnite deposits, New South Wales, Australia and southern New Zealand

Distribution, speciation and availability of antimony (Sb) in soils and terrestrial plants from an active Sb mining area

“…The present results show that the mobility of Sb may be substantial higher in active mining areas like Xikuangshan, indicating a high level of bioavailable Sb in soil. This is also supported by Ashley et al (2003), who found considerable solubility of Sb (up to 37.3 mg L À1 ) in equilibrium studies of stibnite from the Stoker deposit (Otago, Australia) with water (L/S ratio 1.5:1) and in stream sediments downstream the recently mined Hillgrove mine area, Australia (up to 6 mg L À1 ). Moderate Sb mobility (1e129 mg kg À1 ) in water extracts of soil (L/S ratio 10:1, 24 h shaking) from an abandoned Sb mining area in Extremadura, Spain was also found by Murciego et al (2007).…”

Simultaneous removal of Cd(II) and Sb(V) by Fe–Mn binary oxide: Positive effects of Cd(II) on Sb(V) adsorption

“…KSb(OH) 6 exhibited three peaks at 689, 588, and 472 cm −1 , which may be assigned to the stretching vibration of Sb(V) O [19], and these peaks can also be observed in the Cd-Sb(V) precipitate. The peak at 472 cm −1 showed a slight blue shift to 445 cm on Sb(V) adsorption.…”

“…The stock solutions of Sb(V), Cd 2+ , Mn 2+ , and Ca 2+ were prepared by dissolving potassium pyroantimonate [KSb(OH) 6 …”

“…FTIR spectra Fig. 8 illustrates the FTIR spectra of FMBO with adsorbed Cd 2+ and Sb(V) in single-component and coexisting systems, and spectra of FMBO, KSb(OH) 6 , and Cd-Sb(V) precipitate are also shown. The band at 1630 cm −1 was assigned to the deformation of water molecules, and this indicated the presence of physisorbed water on these samples.…”

“…China has the most abundant Sb reserves in the world, and produces approximately 84.0% of the world's supply [5]. The large-scale extraction and utilization of Sb-related minerals has led to serious Sb pollution in some areas [6,7]. Even more serious, the Sb in tailing heaps, waters, and sediments is often observed to coexist with other heavy metals such as cadmium (Cd) [7,8].…”
