Abstract:
Battery paste smelting is the most problematic operation in lead acid battery recycling. For this reason, there have been considerable efforts in the last three decades to find a hydrometallurgical approach to produce lead from paste. Engitec Technologies is continuously updating the CX Technology to design a process more technologically advanced, more environmentally friendly, but also more economically viable.The development of the super-desulphurized paste technology gave us the perfect feed for an electrochemical process. So we resumed studying the possibility to electrowin lead out of this material.In this paper, we will describe our new process based on a chloride electrolyte fed. This technology uses a very unusual E.W. cell that is working at a very high current density and doesn’t require the traditional stripping of the metal.
