“…Indium, a rare and valuable metal [1][2][3], is an important element which is used in the field of electronics [4], energy-related industries [5] and making low melting alloy [6]. Indium has no its own minerals so it has to be recovered as a byproduct from other metallurgical processes [1], together with zinc, lead, copper and tin [6].…”

“…Indium has no its own minerals so it has to be recovered as a byproduct from other metallurgical processes [1], together with zinc, lead, copper and tin [6]. Solvent extraction is a commonly used method for the purification of indium from the zinc hydrometallurgical process [4,7,8]. Thus, the separation efficiency of indium from iron and zinc is of great importance for its purity.…”

Experiments were performed in an interdigital micromixer with 30 microchannels (40 μm width of each channel) to separate In3+, Fe3+and Zn2+from sulfate solutions using Di-(2-ethylhexyl)phosphoric acid (D2EHPA) as the extractant. The effects of pH, extractant concentration and flow rate on the extraction efficiency and flow rate on mass transfer coefficient of In3+, Fe3+and Zn2+were investigated. At a phase flow rate of 7.0 mL/min and initial solution pH of 0.423, the extraction efficiency of In3+, Fe3+and Zn2+was 99.29%, 3.43% and 2.54%, respectively and mass transfer coefficient of In3+, Fe3+and Zn2+was 144.307 s−1, 1.018 s−1and 0.750 s−1. Then, the loaded organic phase was stripped in an interdigital micromixer. At a phase flow rate of 9.0 mL/min and HCl concentration of 160 g/L, stripping efficiency of In3+was 98.92% and mass transfer coefficient of In3+was 169.808 s−1, while concentration of Fe3+and Zn2+was lower than 0.005 g/L with good separation of In3+from Fe3+and Zn2+.

“…Although this device has some merits like a simple structure, low cost and is effective to some extent, there are still problems such as low efficiency [13], too many extraction stages, emulsifying easily [14][15][16][17] and occupation and fire risks [18].…”

The microreactor has been developed for a wide range of applications because of many advantages, such as high mass transfer efficiency, low energy consumption and the closed and safe system. The application of microreactors in the traditional hydrometallurgy extraction process is expected to overcome difficulties such as coextraction of impurities, large consumption of extractant and hidden fire risks. In this study, the extraction and separation efficiency of In 3+ from a complex sulfate solution containing impurities, such as Fe 2+ and Zn 2+ , were studied. The microreactor extraction was carried out in a Pyrex microchip, and the organic phase was prepared with the extractant di(2-ethylhexyl) phosphoric acid (D2EHPA) diluted in 260# kerosene. The results showed that with only 0.55 s contact between the organic and aqueous phases, the extraction ratio of In 3+ can reach 90.80%, while only 0.16% of Fe 2+ and 0.22% of Zn 2+ were co-extracted; the average mass transfer speed of In 3+ was calculated as high as 0.34 g·m -2 ·s -1 . Compared with the traditional mixing settler process, microreactor extraction has advantages of higher extraction ratio of In 3+ , lower trend of co-extraction of the impurities and emulsification.

“…Indium could be extracted by solvents (H 2 SO 4 , HCl, HNO 3 , and di-2-ethylhexyl phosphoric solution). [1,3,5] The chloride-induced vaporization method was also very effective. [6] Waste glass could also be reused in bricks, cement, ceramics, and geopolymer.…”

Transparent conductive glasses such as thin film transistor (TFT) array and colour filter glasses were recovered from the TFT-liquid crystal display panel wastes by dismantling and sonic cleaning. Noble metals (i.e. platinum (Pt)) and indium tin oxide (ITO) are generally used in the cathode of a dye-sensitized solar cell (DSSC). To reduce the DSSC cost, Pt was replaced with nano nickel-encapsulated carbon-shell (Ni@C) nanoparticles, which were prepared by carbonization of Ni²⁺-β-cyclodextrin at 673 K for 2 h. The recovered conductive glasses were used in the DSSC electrodes in the substitution of relatively expensive ITO. Interestingly, the efficiency of the DSSC having the Ni@C-coated cathode is as high as 2.54%. Moreover, the cost of the DSSC using the recovered materials can be reduced by at least 24%.
