Abstract
The recovery of copper wires from automobile shredded residues (ASR) has been investigated using a new dry shaking table that we had developed. The shaking table is shaken in lateral direction while conventional shaking tables such as wet shaking tables and air table in the longitudinal direction. Heavier particles move preferentially in the direction perpendicular to the shaking direction, resulting in the separation of heavier particles from light one.
In this study, we have carried out the separation experiments to recover copper wires from ASR which contained plastics, glasses, rubbers and copper wires. The size fraction of -2+1.18mm was mainly used for this study. The effects of several parameters such as tilts of table, shaking speed and copper content and so forth were examined on the recovery of copper wires from ASR.
At the batch experiment using the sample with Cu grade of 15%, Cu grade and recovery were 50% and 64% under optimum conditions. For continuous separation experiments with 6 time addition of samples, Cu grade and recovery were 56% and 61%.
