“…The latter appears more probable from the results of X-ray analysis. Moreover, among five scientific papers perused, two of them (Freitas and De Pietre, 2004;Shin et al, 2009) report zinc in addition to zinc oxide, but the other three (De Souza et al, 2001, De Souza andFerella et al, 2008) report zinc oxide only. In addition, the wet process of shaking table applied on the paste of batteries should have oxidized most of zinc to zinc oxide.…”

The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C that of Mn 3 O 4 , the main Mn-bearing phase in the mixture. After wet comminution and sieving to remove the anodic collectors and most of the chlorides contained in the mixture, chemical and X-Ray Powder Diffraction (XRPD) analyses were performed. The mixture was heated in CO 2 atmosphere and the temperature raised, thus permitting the zinc oxide to be reduced to metallic zinc by the carbon present in the original mixture. Other tests were carried out by addition to the mixture of activated charcoal (95% C) or of the automotive shredder residue (fluff) containing 45% C.A zinc product was obtained suitable, after refining, for the production of new batteries. The treatment residue consisted of manganese and iron oxides that could be used to produce manganese-iron alloys. From these results, an integrated process for the recovery of the two metals was proposed.

“…Hydrometallurgy has some benefits such as low cost requirements, possible recovery of leachants, and decrease of air pollution as there are no particles produced [11]. The experimental results indicated that in the case of Zn, the efficiency of the hydrometallurgical method is between 73% and 100% [12][13][14].…”

The structural, optical and photocatalytic properties of two zinc oxides prepared from spent alkaline batteries were analysed. After leaching the anode of alkaline batteries, zinc was precipitated from the leachate liquor by introducing oxalic acid (O-ZnO) or sodium carbonate (C-ZnO). The structure of ZnO samples were analysed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), SBET, DRS-UV-Vis spectroscopy and positron annihilation lifetime spectroscopy (PALS). Both oxides present the ZnO wurzite structure and similar morphology. C-ZnO presents a cell lower lattice parameters and bang gap energy (2.99 eV) than O-ZnO (3.05 eV), possibly due to higher concentration of oxygen vacancies. The photocatalytic activity in the degradation of methylene blue (MB) of O-ZnO (achieving 70% MB degradation at 90 min) was superior to C-ZnO, due to its higher surface area and degree of crystallinity and lower bulk/surface defects ratio.

“…The consumption of batteries has increased in the last few decades because of their versatility, low maintenance, and reduced costs, and because of the requirements of the electronics industry [1]. On the other hand, a large quantity of spent batteries has been disposed of as waste.…”

“…Overviews of current techniques, including pyrometallurgical and hydrometallurgical processes and combinations of the two, for the recycling of spent nickel-metal hydride (Ni-MH) and Zn-Mn batteries have been presented elsewhere [1,[4][5][6][7][8][9]. The large energy consumption, high cost, low efficiency, and serious secondary pollution of the traditional techniques make it desirable to find an economic and environmental friendly process to treat and recycle these spent batteries.…”
