“…Data for manganese and zinc are comparable to other literature studies. 2,16 The amount of manganese is higher in alkaline batteries, whereas zinc is more abundant in Zn-C ones. 2 The amount of iron is relatively low.…”

“…2,15 However, this is only true if manganese is solubilized via conversion to Mn(II) by adding a reducing agent. 1,7,13,16,17 Otherwise, manganese leaching is partial. In separate experiments leaching was performed under the conditions described in the experimental section, except that no hydrogen peroxide was added.…”

“…It has been demonstrated that this acid is more efficient than hydrochloric acid. 14 It may be employed alone, 2,4,15 where zinc is preferably leached over manganese, or together with a reductant: H 2 O 2 , 1,2,7,13 SO 2 , 13 oxalate 16 or carbohydrates. 17 In this case, manganese is reduced from + 4/+3 to + 2 state (Mn 2+ , soluble and stable in acidic medium).…”

“…Recovery of the main metals (Mn and Zn) and other elements present in small amounts (particularly iron, usually the major contaminant of the leachate 16 ) was performed by a three-step separation procedure in acidic medium. The overall route presented in this work was compared to those published in the literature about the processing of spent batteries in acidic medium.…”

Recebido em 27/10/09; aceito em 26/4/10; publicado na web em 9/8/10The anode and the internal paste of spent Zn-C and alkaline batteries were leached with 2 mol L -1 H 2 SO 4 at 80 o C for 2 h. Solid/liquid ratio was 1/10 (g mL -1 ). The leachate was treated with Na 2 S in order to precipitate Hg, Cd and Pb. Zn was quantitatively isolated at pH 1,5-2 by adding Na 2 S. Mn can be precipitated at pH close to 7. Na 2 S may be replaced by oxalic acid. Zn precipitated at pH around 0, whereas Mn was quantitatively recovered at pH ≥ 4. Acidity control is a critical parameter. Na 2 SO 4 and carbon are the end products.

“…Alkaline and zinc-carbon spent batteries contain significant amounts of manganese and zinc (Belardi et al, 2011) and their recovery as secondary raw materials (De Michelis et al, 2007) could represent an economic benefit for the battery producers and reduce their environmental impact, as there would be smaller volumes to be disposed of, with an increase in the life of the landfill (Karnchanawong and Limpiteeprakan, 2009). …”

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.
