• Automobile Shredder Residue (ASR) is composed of many kinds of combustible substances but contains a few quantities of copper, which is considered to be a catalyst of dioxins when it is incinerated with chlorine. In this study, a dry tower mill and an electrostatic separator were used to carry out the experiments on the reducing of copper from the agglomerated light ASR materials. It was found that the products after agglomerating the light ASR materials (RDF) could be easily comminuted with 20 kg of steel balls for 20 minutes and the weight percentage of the fraction of −1 mm reached 66.0% at 200 r.p.m while it was very hard to comminute the light ASR materials themselves. Moreover the content of copper in the comminuted product could be reduced from 2.25% to 0.17% by electrostatic separation although the content of other metals such as zinc, lead and aluminum could not be reduced.
