Recovering Palladium from Chloridizing Leaching Solution of Spent Pd/Al2O3 Catalyst by Sulfide Preci chemical composition analysis, and the relevant mechanism was also investigated in this paper. Results showed that when NaOH was previously added to adjust the leaching solution to pH increasing from 1.21 to 4, the recovery of palladium was nearly 100% whilst the dosage of precipitant Na.S decrease

Recovery of Critical Rare Earth Elements for Green Energy Technologiesmplications and certain education to undeveloped countries. As per the Department of Energy (DoE), US the following rare earth elements (REEs) were under critical situation: Dy, Y, Nd, Tb, Eu, in another two namely Ce and Te under near to critical matrix. It shows that REEs scarcity for industry as

Selective Separation of Rare Earth Chlorides Utilizing Vapor Phase Extraction condensate collection. The ceramic tube sections and stainless steel wool were leached in 18 MΩ water. Analysis of the leachate samples revealed that selective separation had occurred but oxychlorides were detected in the non-volatile matter.

Challenges in the Electrolytic Refining of Silver—Influencing the Co-deposition Through Parameter Corolyte composition, as well process parameters like current density and pH on the electrorefining. The applied electrode potential and therefore the applied current density shows great influence on the dissolution behavior of more noble metals than Ag at the anode. At the cathode, the applied curren
