Abstract: Disclosed are solutions for the recovery of elemental metals at industrial scales without smelting including, for example, the recovery of near-pure lead from recycled LABs via specialized electrolytic processing. Further disclosed are new processes, innovative electrolyzer designs, and/or novel utilization of supplemental chemicals necessary for successful electrolysis of pure metal from impure forms (e.g., pure lead from lead oxides), and especially applicable for solid-state electrolysis of mixtures comprising lead paste, electrolyte, and supplemental chemicals. With particular regard to recovering near-pure lead during LAB recycling, solid-state electrolysis of mixtures comprising impure lead (e.g., lead paste) is made possible and scalable to industrial levels via utilization of a vertically-arranged series of two-compartment horizontal cathodes or two-compartment horizontal bipolar cathodes in an electrolyzer assembly to simultaneously produce, for example, elemental lead (Pb), sodium hydroxide (NaOH), and chlorine gas (Cl2).

Abstract: In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

Abstract: The electrolysis of cuprous chloride was carried out in the electrochemical cell. The particle size, current density, cathodic current efficiency, conversion of cuprous chloride and yield of copper formed depends strongly on current flow, heat transfer and mass transfer operation. The current flow, heat transfer and mass transfer are depends on surface area ratio of anode to cathode, distance between electrodes, concentration of HCl, applied voltage, flow rate of electrolyte, CuCl concentration and reaction temperature. The electrolysis of cuprous chloride as a part of Cu—Cl thermochemical cycle for hydrogen production is experimentally demonstrated in proof-of-concept work.
