| titleOfInvention | METHOD FOR RECOVERING METALS FROM SMALL BATTERIES |
| abstract | The method comprises the hydrometallurgical processing of spent small batteries for the purpose of recovering metals, in particular mercury, silver, gold, and the Edelstahlgehaeuse. In accordance with the method, the small batteries are subjected to nitric acid leaching with 350 to 500 g HNO 3 / l, via wet sieve and filtration stages a largely selective separation into coarse solids (stainless steel casing), fine solids (gold, manganese dioxide) and into a Hg- and Ag-containing Achieved solution, from which by several chloridic Faell- and Loesestufen a Hg-containing and an Ag-containing product are obtained. The method makes it possible, without thermal and / or mechanical pretreatment of the small batteries, to carry out a separation of the value components and their accumulation in products which allow a simple classification into known technologies. The process can be carried out in conventional wet metallurgical plants. |
