The recovery process of selenium from Iranian Sar-Cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. The copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium. They are being extracted as a by product in th...

The development of the population’s well-being involves use different raw materials. However, metallic elements such as copper are currently scarce due to their intensive in sectors. Therefore, new sources materials that provide these elements, lower cost, and waste for extraction must be sought. For this reason, research, dumps mining district Linares (Spain) studied evaluate existence recover...

Germanium-containing residues (GCR) are a secondary resource rich in zinc (Zn) and germanium (Ge) produced the Zn pyrometallurgical process an important raw material for recovering Ge. To recycle residue by hydrometallurgy, sulfuric acid is used to leach under normal pressure. In this study, experimental conditions (leaching temperature, leaching time, liquid/solid (L/S) mass ratio initial acid...

With the widespread adoption of e-mobility, there are high numbers lithium Ion batteries (LIB) entering waste stream. It is imperative that disposal and recycling strategies developed implemented. There an urgent need for safe, environmentally friendly economically affordable routes End Life (EoL) LIBs. This study has looked at 44 commercial recyclers assessed their reclamation processes. A nov...

Peculiar chemical, mechanical, and magnetic properties make cobalt a key metal for variety of “hot” applications like the cathode production Li-ion batteries. Cobalt is also preferred metallic binder tungsten carbide tool manufacturing. The recent increasing criticality driving interest manufacturers researchers toward high-rate recycling hard-metal (HM) waste limiting demand raw materials. A s...

Lithium-ion batteries have become a crucial part of the energy supply chain for transportation (in electric vehicles) and renewable storage systems. Recycling is considered one most effective ways recovering materials spent LIB streams circulating material in critical chain. However, few review articles been published research domain recycling circular economy, with mainly focusing on either me...

Since Pourbaix presented Eh versus pH diagrams in his “Atlas of Electrochemical Equilibria in Aqueous Solution”, diagrams have become extremely popular and are now used in almost every scientific area related to aqueous chemistry. Due to advances in personal computers, such diagrams can now show effects not only of Eh and pH, but also of variables, including ligand(s), temperature and pressure....

A new database was developed to successfully model the solid and aqueous phase equilibria in a number of hydrometallurgical processes using the Mixed Solvent Electrolyte (MSE) model of the OLI Systems software. In order to validate the predictability of the model developed, a number of experimental measurements were conducted in multicomponent solutions containing NiSO4, H2SO4, MnSO4, HCl, etc....
