Although many technologies have been introduced to recover valuable metals from copper
slags, their economic and environmental compatibilities were not satisfactory. The …

This study investigates the ultrasound-assisted leaching of Li and Co from spent batteries
using a deep eutectic solvent (DES) composed of polyethylene glycol and thiourea. The …

Copper smelting flue dust (CFD) is a byproduct of pyrometallurgical copper production,
containing valuable metals like lead, zinc, and copper, but also hazardous arsenic, which …

The study investigates the application of high-voltage electrical pulses (HVEP) as a
pretreatment to enhance the leaching efficiency of rare earth elements (REE) from coal ash …

The dissolution behaviors of Cu and Fe from copper slags were investigated with
photochemical reactions. Experiments were run intermittently with a quartz glass jacket in a …

In this study, SDS is used to enhance the sulfuric acid leaching of chalcopyrite in aqueous
and isopropanol media. The presence of SDS increased copper extraction into the solution …

Iron in the form of fayalite in copper tailings poses a challenge for traditional beneficiation
methods due to its fine particle size. In this work, iron present in copper tailings was …

The dissolution behaviors of metals from copper slag, were investigated at atmospheric
pressure using hydrogen peroxide and acetic acid. The slag was a mixture of converter and …
