efficient gold chlorination process

Recycling gold and copper from waste printed circuit

Chlorination is a feasible alternative for the recovery of metallic elements due to the higher dissolution rate, non polluting character and selective leaching of different metals by controlling the redox potential. In the present study, an efficient and less polluted chlorination process to recycle gold and copper from waste PCBs was investigated.
