Summary: Physicochemical and electrochemical properties of N,N,N-dimethylbutylammonium methanesulfonate, [DMBA][MS], ionic liquid (IL) have been determined, and the potential application for electrochemical recovery of lead from lead-acid batteries is discussed. The molar conductivities obtained from the molar concentration and ionic conductivity measurements were used to quantify the ionicities of these IL mixtures. Preliminary results of the electrochemical kinetics of Pb-II reduction showed fast Pb deposition and potential-controlled electrodeposition morphologies of Pb, which may be advantageous for the design of up-scaled lead electrowinning processes.

Summary: This paper investigates a two-step leaching and electrowinning process using acetic acid for the recovery of lead (Pb) from end-of-life solar modules. It is found that acetic acid with hydrogen peroxide can dissolve Pb quickly, in a matter of minutes under certain conditions. The study demonstrates successful Pb electrowinning from aqueous solutions of lead(II) acetate with 0-10% v/v acetic acid. The presence of metallic Pb and Pb(II) oxide co-deposits on the cathode, as well as lead subacetate and lead(IV) oxide deposits on the anode, is confirmed through various analytical techniques.

Summary: This paper presents an innovative and efficient process for the hydrometallurgical recovery of lead paste, which improves the leaching efficiency of lead by converting PbSO4 in the lead paste into acid-soluble Pb3(CO3)2(OH)2 or NaPb2(CO3)2OH in Na2CO3 solution. Under optimized conditions, a dense and flat lead plate with purity greater than 99.99% can be obtained, and the total lead recovery ratio in the whole process can reach 95.28%.

Summary: In this study, a novel IrFe/nitrogen-doped pyrolytic carbon black composite was proposed as an oxygen evolution reaction (OER) catalyst for the methanesulfonic acid (MSA) electrolytic system. The catalyst demonstrated advanced OER catalytic efficiency and selectivity due to its thoughtful design, which increased the specific surface area and enhanced the number and uniformity of Ir and Fe species. The optimized IrFe/NCBp composite showed superior OER performance and excellent durability compared to commercial catalysts. It effectively reduced the electrolytic voltage and achieved efficient Pb recovery.

Summary: Chalcopyrite leaching with novel lixiviants, such as ionic liquids, glycine, and methanesulfonic acid, shows varying chemical effectiveness and economic potential. While ionic liquids offer rapid extraction rates but require high concentrations and are costly, glycine and methanesulfonic acid present cheaper options with diffusion-controlled rates but face challenges such as reagent consumption and the need for fine grinding. Hypochlorites perform comparably to ferric chloride without high reagent concentrations, but all novel lixiviants provide valuable insights into chalcopyrite dissolution behavior in different chemical systems for future research.

Summary: The addition of iodide was found to accelerate chalcopyrite leaching in ferric sulfate media at ambient conditions, with solution potential playing a key role in controlling the iodine speciation. Experimental results showed that increasing solution potential, iodide concentration, and temperature can enhance copper dissolution rate. A kinetic model was developed linking copper extraction rate to solution potential, diiodine concentration, and temperature, supporting that the leaching process is controlled by surface chemical reaction.

Summary: This paper describes fundamental studies on the integration of CO2 mineralization and selective metal extraction from natural olivine. The results show that nearly 90% of nickel and cobalt extraction and mineral carbonation efficiency can be achieved through a highly selective, single-step process. The introduction of a metal-complexing ligand aids in the selective extraction of Ni and Co over Fe and Mg. This study provides a framework for further development of direct aqueous mineral carbonation with concurrent EMR.

Summary: A selective and highly effective method for the extraction and separation of V(IV) and Fe(III) using N235 and P507 as solvent extractants is proposed. The pH, composition, and concentration of the extractant mixture have significant effects on the extraction efficiency and separation factor. The mixing of P507 and N235 generates the P507 monomer, which enhances the extraction efficiency and weakens the stability of vanadium containing extraction complex. Cation exchange process forms the extraction complexes.

Summary: A first principles model is developed to describe the dissolution mechanism of phosphate ore particles in a solution of phosphoric acid. The model accounts for non-uniform size of ore particles using particle size distributions and quantifies their influence on the model predictions. A global estimability analysis is carried out to determine the estimable parameters from experimental data, and the predictions show good agreement with the experimental data. The computed activation energy indicates that diffusion is the rate limiting step of the dissolution process.
