Processing of spent zinc-carbon and alkaline portable batteries
Original language description
Kovohutě Příbram has developed technology of portable zinc carbon and alkaline batteries treatment. Technology consists of their crushing, sorting components and their utilization. To comply with new goals for recycling efficiency set by Directive 2006/66/EU VSCHT Praha develops hydrometallurgical method to utilize the electrode material, which is the key factor to fill the goal. Present work describes method of batteries treatment used and in details especially results of tests of hydrometallurgical treatment of active mass originated from spent Zn/MnO2 batteries after their dismantling. The active mass is leached in sulfuric acid originated from spent lead acid batteries; the leach liquor is purified and by alkalization is possible to get zinc carbonate usable for zinc production or other purposes.
