Abstract
It is very important to recycling of polymer‐insulated copper wire to remove copper from the wire without any contamination. A rolling machine and a blender were used to separate and recover the copper wires from a polymer coated cable. In the experiment using a rolling machine, the recovery of copper was improved by an increase in the number of rolling times and by lowering the cable temperature. All of the copper was recovered from a cable of 115 K in temperature. In the other experiment using a blender, the weight of the recovery of copper was increased by shortening the cable length and by increasing the rotary speed of the blender and the treating time. All the copper in a cut cable of 3mm long was recovered from a cable.
