Metal Reclamation Technology in Electroplating
A Hungarian SME offers an equipment for recovering metals, applied in electroplating technique of surface treatment. It can be used to recover the metal waste, which arises during the silver-, copper-, tin-, nickel-, eventually zinc plating process and it can be recycled into the electroplating process. The investment returns in 3 or 4 years. The equipment was designed for recovering all the metal ions from the flushing water. Along the galvanic line, 90% of the galvanic solution sticked to the metal surface aggregates in the economy rinsing vat while the rest 10% comes to the stream rinsing vat. The aim is to recover all metal ions from the solution aggregated in the economy rinsing vat (90% of the total loss). This aim can be reached by electrolysis. As metal ions remain in the solution after the process, the solution is reverted and the electrolysis is repeated. This technology can be used for chloride ion free and chlorid containing solutions, as well. Further results are the reduction of the quantity of galvanic sludge during the process and easy reuse of the metal recovered.
