ÖzBu çalışmada, atık alkali pillerden glukonik asit ve hidroklorik asit ile çinko ve mangan elementlerinin solüsyona alınabilirliği incelenmiş ve Taguchi deneysel tasarımı ile oluşturulan deney düzeneği ile sonuçlar istatiksel olarak değerlendirilmiştir. Taguchi deney tasarım şartlarına göre 3 farklı değişken ile 3 farklı konsantrasyonda (3*3) çalışılmıştır. İki farklı Taguchi deneysel tasarımı oluşturulmuştur. Birinci Taguchi deneysel tasarımında değişken olarak glukonik asit, sıcaklık, deney süresi seçilmiştir. İkinci Taguchi deneysel tasarımında ise değişken olarak glukonik asit, hidroklorik asit ve deney süresi seçilmiştir. Deneysel çalışmalar sonucunda, asit olarak sadece glukonik asitin kullanıldığı deneysel çalışmalarda, yüksek glukonik asit konsantrasyonlarında mangan gideriminin daha iyi olduğu; bununla birlikte glukonik asit ve hidroklorik asitin birlikte kullanıldığı durumlarda düşük konsantrasyonda glukonik asit ve düşük konsantrasyonlarda hidroklorik asit ile daha iyi giderimler elde edildiği görülmüştür. Tüm deneysel çalışmalarda etkili bir çinko giderimi elde edilememiştir.Anahtar Kelimeler: Çinko, Glukonik asit, Hidroklorik asit, Mangan, Taguchi yöntemi Investigation of Manganese and Zinc Removal with Gluconic Acid and Hydrochloric Acid from Waste Alkaline Batteries: Taguchi Experimental Design AbstractIn this study, the leaching of zinc and manganese from waste alkaline battery powders with gluconic acid and hydrochloric acid was investigated. The results were evaluated statistically with Taguchi experimental design. Taguchi experimental design conditions was conducted at 3 different concentrations (3*3) with 3 different variables. Two different Taguchi experimental designs were created. In the first Taguchi experimental design, gluconic acid, temperature, reaction time were chosen as variables. In the second Taguchi experimental design, gluconic acid, hydrochloric acid and reaction time were selected as variables. Experimental studies have shown that manganese removal is better at high concentrations of gluconic acid in experimental studies where only gluconic acid is used as the acid; while the lower concentration of gluconic acid and hydrochloric acid was sufficient when being used in combination. There was no effective zinc removal was achieved in all experimental runs.

“…This process is essential to accelerate the rate of metal dissolution (Sayilgan et al, 2009a). Pyrometallurgical process is the most widely applied technology in recovering metal from spent batteries (Sayilgan et al, 2009a;Belardi et al, 2012). Pyrometallurgy is a thermal treatment process, which involves volatilisation and condensation of metal.…”

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.
