Electrolysis
In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potThe extraction of metals depends on the difference in chemical potentials which makes the separation of metal values from the compounds difficult.

Electrolytic extraction of yttrium using recycle liquid gallium
The main purpose of this paper is to study the extraction and separation of key fragment elements based on the electrolytic refining process of spent fuel dry reprocessing. Firstly, the electrochemical mechanisms of Er(III) and Yb(III) in LiCl-KCl molten salts were investigated on W and In film electrodes with applied cyclic The key to IAP for the separation is thus a difference in metal ion solubilities, Lang, J. et al.

Separation of lithium, nickel, manganese, and cobalt from
During metal separation, Ni and Co were separated using electrodialysis coupled with EDTA and then Li was separated from Mn using electrodialysis with a monovalent CEM. Furthermore, the separation of different metals through the ion-exchange membranes was studied using electrochemical impedance spectroscopy (EIS) The separation and recovery of tungsten and cobalt from cemented tungsten carbide (WC-Co) scraps can be carried out by adding WO 3 and CoO into the Na 2 WO 4 molten salt to simulate the calcination of WC-Co scraps. The Raman spectra and the XRD patterns of the molten salts cooled naturally to room temperature, and the Electrolytic separation of cobalt and tungsten from cemented

Recovery and separation of rare earth elements by molten salt
With the increasing demand of rare earth metals in functional materials, recovery of rare earth elements (REEs) from secondary resources has become important for the green economy transition. Molten salt electrolysis has the advantages of low water consumption and low hazardous waste during REE recovery. This review systematically The flakes removed from the cathode of the electrolytic cell are then heated to 500 °C, which produces electrolytic manganese powder. 27 Electrolytic manganese was added to the NDS in 2019. 14 Although recycling manganese outside of metal alloy scrap is not common, it has been recovered from batteries using thermal treatments and chemical Electrochemical methods for materials recycling RSC Publishing
