The International Copper Study Group (ICSG) released preliminary data for April world copper supply and demand in its June 2025 Copper Bulletin. ICSG noted that preliminary data indicates that world ...

Our EV makers face a rare-earth magnet scarcity while the country faces a steep challenge in securing local supplies of ...

Direct lithium extraction from α-Spodumene using NaOH roasting and water leaching. Chemical Engineering Journal, 2025; 505: 159661 DOI: 10.1016/j.cej.2025.159661 ...

A new copper pressure oxidation (Cu POX) leaching process aims to address the changing needs of the copper extraction industry, faced by the ongoing depletion of deposits and increasing ...

Solventless concentrates, especially rosin, are gaining popularity for their purity and flavor, reflecting a shift towards natural extraction methods in the cannabis industry.

The pre-designed process and equipment package enables fast ramp-up to production and integrates with solvent extraction and electrowinning (SX – EW) infrastructure. The Cu POX plant can also be ...

This generates a copper-bearing pregnant leach solution (PLS) that undergoes further processing through solvent extraction and electrowinning (SX-EW), producing high-purity London Metal Exchange (LME) ...

The PLS would be further treated in solvent extraction and electrowinning processes, from which copper is recovered as high-purity LME Grade A cathodes.

The use of solvent extraction to recover metals and water from industrial residues is highlighted in this work. The method was applied (1) to selectively concentrate Zn from effluents generated by the ...
