In this study, ammonium phosphate ((NH<sub>4</sub>)<sub>3</sub>PO<sub>4</sub>) was employed to realize improvement by modifying the physical characteristics of malachite surface, ensuring sustainable flotation throughout operations, and enhancing process be more stable. Furthermore, various techniques, including X−ray photoelectron spectroscopy, were intensel...

The electrical contact resistance of a Ag/carbon nanotube (CNT) composite plating film prepared using cyanide-free bath was evaluated against H2S gas corrosion test. After the test, Ag/CNT exhibited lower than Ag for comparison. mechanism superior characteristics investigated various methods. Scanning electron microscopy observations and X-ray diffraction analyses revealed that amount silver su...

Processes for recycling lithium ion batteries (LIB), in particular complex chemistries such as those containing nickel-manganese-cobalt oxide (NMC) cathodes are hindered by tradeoffs between capital cost, process sustainability, and materials recovery. Most metal separations primary secondary production of critical elements rely on anion exchange chemistries. Herein, we explore the application ...
