PCT No. PCT/CH95/00136 Sec. 371 Date Oct. 29, 1996 Sec. 102(e) Date Oct. 29, 1996 PCT Filed Jun. 16, 1995 PCT Pub. No. WO95/35583 PCT Pub. Date Dec. 28, 1995A process of recycling unsorted batteries. The unsorted batteries are led from a feeding bunker through a shredder directly into a rotary furnace as they arrive from the disposal collection. The shredded batteries are oxidatively burned at a temperature from 400 DEG C. to 900 DEG C. The resulting combustion gases are led via a gas cleansing installation consisting of a dust filter, wet washing filter and active charcoal filter. The oxidized product of combustion resulting from the combustion is fed to a metal winning process. The product of combustion may be burned once again in a further or later step by the rotary furnace after mixing with a reducing substance, coal, after which the resulting reductive product of combustion may again be fed to the metal winning process. |
