Recovery of zinc and manganese from alkaline and zinc-carbon …
Concerning the selective recycling of alkaline batteries, Veloso et al. [9] proposed a process in which the metals are leached by H 2 SO 4 and H 2 O 2, then manganese and zinc are precipitated selectively by KOH. De Souza and Tenorio [10] described another process for the recovery of zinc and manganese by an acid leaching; …
Recycling Technologies of Zn–C Batteries: Review and ...
Among the primary batteries, the most commonly used are zinc-carbon and alkaline-manganese. These batteries usually come in sizes AAA, AA, C, D, and 9 V. Zn–C batteries have been studied for hundreds of years. The two types of Zn–C batteries most used are those of Leclanché and those of the zinc chloride system.
