<p>A considerably simplified process is disclosed for reducing equipment costs for carrying out a recycling process of non-sorted batteries. The non-sorted batteries, just as they are collected, are directly supplied from a feeding hopper (1) to a rotary furnace (3) through a shredder (2). The shredded batteries are oxidatively burnt at a temperature from 400 ~C to 900 ~C during preferably 45 to 90 minutes. The combustion gasses produced flow through a gas scrubbing plant (7) that consists of known elements: dust filter (4), wet scrubbing filter (5) and active coal filter (6). The oxidised combustion product (P) is recycled by a metal recycling process (8). The combustion product (P) may be burned once again in an additional or subsequent step in the rotary furnace (3) with admixture of a reducing agent, coal. The thus obtained reduced combustion product may in turn be recycled by a metal recycling process (8).</p> |
