“…Common methods for the analysis of indium include voltammetry, [ 23 ] atomic absorption spectroscopy (AAS), [ 24 ] and inductively coupled plasma atomic emission spectroscopy (ICP–AES). [ 25 ] However, these methods are often not widely used because of expensive instrumentation, low sensitivity, complicated sample preparation, and high sample requirements.…”

Based on thieno[2,3‐b]quinoline‐2‐carbohydrazide and salicylaldehyde, a novel fluorescent probe (L) was designed and synthesized. L could be used as a multifunctional sensor to sequentially detect In3+ and Fe3+ through fluorescence enhancement and fluorescence quenching in DMF/H2O buffer solutions. At the same time, L had good anti‐interference ability, which could still detect In3+ and Fe3+ well in the presence of other metal ions. For F−, it could be detected by enhancing the fluorescence change caused by the introduction of Al3+. When other anions were present, the detection of F− would not be interfered. The detection limits of In3+, Fe3+ and F− were 1.16 × 10−10 M, 2.03 × 10−8 M and 7.98 × 10−9 M, respectively. The complexation model and sensing mechanism between L and In3+, Fe3+ and F− were confirmed by calculating structural optimization and energy optimization using Gaussian 09 software.

“…As part of extractive metallurgy, hydrometallurgy is a well-established process which is applied successfully for metal leaching from both primary and secondary resources [22,26]. Nowadays, several researches are being undertaken on chemical leaching of critical metals including REE [26][27][28][29], base metals [30][31][32][33] and precious metals [34][35][36] from e-waste materials. The process is mainly divided into three steps (leaching, solid liquid separation/purification and metal recovery).…”

“…Different groups of lixiviants such as inorganic acid [30,31,33,38], organic acid [27,36] and alkaline reagents [36,[39][40][41], are used for metal leaching from e-waste. Recently, several reports were made with respect to REE and precious metals [26,37,[42][43][44].…”

“…Hydrometallurgical processes have been used as an important tool in several researches that were recently carried out for metal leaching from liquid crystal display (LCD) panels. The majority of these studies focus on the recovery of indium from LCD [27,[57][58][59]. It is important to note that indium is basically and primarily recovered as a by-product of zinc through the processing of base metal concentrates [70].…”

A Review on Chemical versus Microbial Leaching of Electronic Wastes with Emphasis on Base Metals Dissolution

et al. 2021

There is a growing interest in electronic wastes (e-wastes) recycling for metal recovery because the fast depletion of worldwide reserves for primary resources is gradually becoming a matter of concern. E-wastes contain metals with a concentration higher than that present in the primary ores, which renders them as an apt resource for metal recovery. Owing to such aspects, research is progressing well to address several issues related to e-waste recycling for metal recovery through both chemical and biological routes. Base metals, for example, Cu, Ni, Zn, Al, etc., can be easily leached out through the typical chemical (with higher kinetics) and microbial (with eco-friendly benefits) routes under ambient temperature conditions in contrast to other metals. This feature makes them the most suitable candidates to be targeted primarily for metal leaching from these waste streams. Hence, the current piece of review aims at providing updated information pertinent to e-waste recycling through chemical and microbial treatment methods. Individual process routes are compared and reviewed with focus on non-ferrous metal leaching (with particular emphasis on base metals dissolution) from some selected e-waste streams. Future outlooks are discussed on the suitability of these two important extractive metallurgical routes for e-waste recycling at a scale-up level along with concluding remarks.

“…Continuous technological progress requires deliveries of metals, of which the natural resources in the Earth's crust are being successively depleted. Hence, a very important element of metallurgy consists in the effective recovery of metals from products withdrawn from use or from the process waste [1][2][3][4][5][6][7][8][9]. Metallic scrap most frequently comprises a few precious metals; therefore, methods for their recovery are of a many-stage and selective nature.…”

In leaching processes controlled by diffusion and convectional transport of mass, the hydrodynamic structure formed in the reactor’s working volume is an additional factor affecting the process. This research work presents results related to hydrodynamic structures developing in batch reactors, different in shape, recorded by means of the particle image velocimetry (PIV) method. The movement of the distilled water and leaching solution was analyzed during investigations. Next, the system hydrodynamics and the process of tin leaching were analyzed. Finally, the leaching is affected by the reactor geometry and the hydrodynamic structure developed in its working volume, especially when a convectional or diffusion mass transport decides the process efficiency.
