Iron removal from sulphate liquors after hydrometallurgical processing of waste Zn/MnO2 batteries
Original language description
Iron is usually present in leach solutions and its elimination is a major operational problem in zinc hydrometallurgy. The aim of this work was to compare the course of iron precipitation from sulphate leach liquors depending on pH and neutralizing agents. These solutions containing about 44 g /dm3 Zn, 15 g/ dm3 Mn, 0,5 g/dm3 Fe and negligible content of Cu, Ni and Cd originated from leaching electrode materials from waste Zn/MnO2 batteries in H2SO4. Decrease of iron concentration was studied during pHadjustment by solid K2CO3 and/or Na2CO3 and also electrode materials of different grain size. In the case of using electrode material as a neutralizing agent the iron precipitation was completed at pH about 3,5 whilst iron precipitation using Na2CO3 wascompleted at pH about 4,0. Grain size of used electrode materials did not affected iron precipitation rate. Further advantage of using electrode material as a neutralizing agent is in better filterability of the precipitates obtained comp
