Simple method to recycle waste batteries

Recycling waste batteries process has the following steps:
1. Category. Recycling of waste batteries will be smashed, stripped and dell c1295 at the end of the shell of zinc iron, copper cap and remove the graphite rod, and the remaining black material as the core of the manganese dioxide battery and a mixture of ammonium chloride, the above-mentioned substances were collected and concentrated processing, can be some useful material. Its graphite rods by washing, drying and then used as electrodes.
2. System zinc tablets. Will be stripped of the zinc shell of cast iron wash pot placed after the heating and melting heat for 2 hours, remove the top scum, poured cool, drop in the iron,inspiron 1100 battery, the question was zinc tablets after solidification.
3. Recovery of copper. Copper cap after flattening washed with hot water, inspiron 5100 battery, then adding a certain amount of 10% sulfuric acid boiling for 30 minutes to remove the surface oxide layer, remove wash and drying that is a copper.
4. Recovery chloride. Add the black cylinder of material, by adding the warm water 60oC stirring 1 hour, so that all ammonium chloride dissolved in water, static, filtration, washed 2 times dregs collected mother liquor; vacuum distillation in the mother liquor to crystal surface appears white until ,latitude d620 battery , cooling, filtration was ammonium chloride crystals, mother liquor recycle.
5. The recovery of manganese dioxide. After filtering the dregs will be washed 3 times, filtration, filter cake into the pot a little dry to remove carbon and other organic material, then put the full mixing in the water for 30 minutes, filtering,inspiron e1505 battery , will be cake baking in 100-110oC, that is, a black manganese dioxide.
