“…Some specific trace elements such as Fe, Cu, Zn, Mn, Co, Mo, Ni, W, Se, B, play an irreplaceable role in the synthesis of essential coenzymes or cofactors in methanogenic pathways. Plenty of significant investigations of the requirement of trace elements for anaerobic digestion process have been carried out and reported in recent years (Takashima and Speece, 1989;Takashima et al, 1990;Ward et al, 2008;Zhang et al, 2014). Zandvoort et al (2006), Fermoso et al (2009), andSchattauer et al (2011) reviewed the general functions of metalloenzymes involved in the metabolic pathways of methanogenesis and summarized the recommended or stimulating concentrations of trace elements in anaerobic digesters.…”

“…The investigated mechanisms of SMA increasement including biomass increasement, functional archaea increment by abundance and size in the work. But there are still further mechanisms researches needed in activity of metal-enzymatic (Sambusiti et al 2014;Scheller et al 2010) and bioavailability of trace metals (Vintiloiu et al 2013).

“…The TE supplementation concentrations were calculated on TE ion concentration in solution which was regarded as approximately bioavailable form (Vintiloiu et al 2013 To make results more comparable in these test groups, all effects of TEs on methanogenesis were calculated as percentage (Strömberg et al 2015); such as, effect of TE supplementation on methane production was calculated as Eq.

For enhancing anaerobic membrane bioreactor (AnMBR) treating food processing wastewater due to speedlimited methanogenesis step, multiple effects of trace element (TE) supplementation on methanogenesis of a two-phase AnMBR were firstly investigated in batch tests. TE supplementation included individual element, combination and recovery of Fe, Ni, Co, Cu and Zn supplementation. Multiple effects of TE supplementation were highest stimulated by 22.4 ± 5.6 % (TE313) for chemical oxygen demand (COD) removal, 43.1 ± 12.5 % (TE303) for specific methanogenic activity (SMA) and 13.9 ± 3.7 % (TE405) for biomass growth, respectively, although only 7.5 ± 0.6 % (TE106) for methane production. Dosage of TEs played a critical role in methane production, COD removal and biomass growth of the AnMBR's methanogenesis. Low dosages of TE supplementation improved the COD removal and slightly stimulated the COD bioconverting to methane and biomass, but their specific methanation activities were inhibited in the initial rapid methanogenesis stage. Several methanation functional species were increased in abundance like Methanosarcina and Methanoculleus.

“…Hence, the extraction yield of metals was found to be dependent on the Although there are differences in the rate of metal extraction with EDTA, EDDS and HIDS, the differences are not significant except under highly acidic and strongly basic conditions. In spite of the higher efficiency of EDTA, its poor photo-, chemo-and biodegradability evoke environmental concerns [34][35][36][37], and the biodegradable alternatives (EDDS or HIDS) deserve consideration [38][39][40]. The extraction of Pb and Zn from solids with EDDS was observed to be Chemical Engineering Journal, 277: 219-228, 2015 The original publication is available at: http://dx.doi.org/10.1016/j.cej.2015.04.112 11 superior to extraction with HIDS under basic conditions [40], and EDDS has been selected for subsequent studies.…”

Non-ferrous smelting dust, especially lead-smelting dust (LSD), contains percent levels of indium and thus constitutes a novel indium resource. The main difficulty in recovering indium from LSD is the coexisting presence of lead and zinc. In this study, a unique indium separation process was designed, combining techniques that involve washing with a chelant, leaching with acid and precipitation as hydroxide. The majority of the Pb in the LSD was selectively separated during chelant-assisted washing with ethylenediaminedisuccinate (EDDS), while the residual Pb was diminished through an acid leaching treatment with a mixed solution of sulfuric acid and hydrochloric acid. The chelant washing step also ensures a decrease in the raw LSD weight at a ratio of approximately 82 % due to the removal of lead and counterions such as sulfate, and the washing step also minimizes the consumption of corrosive acids in the subsequent step. Selective indium separation from LSD is further complicated by the similarity of the behavior of zinc during the acid leaching step. Therefore, hydroxide precipitation at pH 5 has been introduced as the final step, ensuring the maintenance of zinc as a soluble species in the supernatant and the selective separation of indium (∼ 88 %) as a hydroxide precipitate.

ITO is widely utilized for manufacturing liquid crystal displays, plasma displays and solar energy cells [2], which consume approximately two-thirds of the global indium production [1]. One of the resource materials for raw indium is non-ferrous metal ore [3], which is obtained as a by-product of the smelting process of the non-ferrous metal ore [4]. Raw indium deposits are region-specific (i.e., China, Korea, and Russia) [5]. Discrepancies in demand, supply and price are therefore observed. The search for alternate sources of raw indium is vital from the point of view of resource strategy, and this search is focused mostly on the processing of indium-laden waste materials, e.g., ITO scrap [2, 6-8], end-of-life liquid crystal displays [6,[9][10][11] and etching waste [12][13][14].The residue and flue dust from the smelting of non-ferrous metals, such as lead, termed lead smelting dust or LSD hereafter, also includes indium [15] and is expected to be a novel indium resource. Acid leaching is commonly employed for metal smelting from waste resources [16][17][18].Indium recovery from waste material has been reported through the use of acid leaching and hydroxide or sulfide precipitation [2,6,7,[19][20][21]. This approach is frequently criticized both in terms of overall efficiency d...
