“…However, some of the analyses were above the minimum detection limits and this suggests that small fractions of the Bi, Sb, As and Pb in Anode-C are present in dilute solid solution in the copper crystals. These results are similar to those observed for anodes from other copper refineries [12][13][14][15]. Figure 2 illustrates the most common morphology of the impurity particles which occur along the copper grain boundaries in Sb-rich Anode-A.…”

“…Although the spectra of the refinery electrolyte were also noisy, because of the low Sb concentration involved (<300 mg/L Sb), fitting of the L-111 XANES spectra indicated that about 60% of the dissolved antimony was present as Sb(III) and 40% as Sb(V). These values are in close agreement with those obtained on the same electrolyte using selective ion exchange to retain Sb(V) and ICP analysis of the eluted Sb(III) [15]. In all instances, the results for antimony speciation in the anode, anode slimes, leached anode slimes and electrolyte samples should be considered as preliminary.…”

“…The question arose whether similarities between Sb and As speciation and fate in solution could be exploited to effectively attenuate Sb-polluted mine-impacted waters. Ion exchange resins are widely used to treat As-contaminated waters and several commercially-available ion exchangers can be used to remove Sb from aqueous solution, although efficient Sb removal via ion exchange can be problematic due to differences in Sb speciation (McKevitt and Dreisinger 2009;Riveros et al 2008). The removal of Sb and As oxyanions by conventional strong-base ion exchangers may be significantly hampered by the presence of other anions, such as sulphate, chloride, nitrate, and others, which compete for available binding sites on the resin (Sylvester et al 2007;Ungureanu et al 2015).…”

“…Numerous studies document the successful recovery of metals from ion-exchange resins and subsequent resin regeneration and reuse (e.g. McKevitt and Dreisinger 2009;Nikoloski and Ang 2014;Petruzzelli et al 1995;Riveros et al 2008;Sarkar et al 2007;Selvi et al 2004). In addition to Sb removal from aqueous solution to extremely low residual concentration, an advantage of ion exchange resin use for mine water purification is the relative ease of recovery of adsorbed ions.…”

“…Other techniques have been proposed to control antimony concentrations in copper electrolytes, including precipitation [15], adsorption [16,17] and ion exchange [18]. Ion exchange resins are used in several copper refineries [19,20] to remove Sb and Bi and maintain their concentrations below 0.50 g L −1 in commercial electrolytes [21,22], although the concentrations of these elements can increase due to the high impurities content in copper anodes [23].…”
