extraction of copper from copper oxide

Biosynthesis, Characterization and Photocatalytic Activity

12.04.2019 · The paper presents a green, simple and eco-friendly method to synthesize copper/copper oxide nanoparticles (Cu/CuO-NPs) from CuSO 4 solution using aqueous extract of lemongrass leaf as the reducing and capping agent. The influence of some factors such as the volume ratio of lemongrass leaf extract and CuSO 4 solution, pH and temperature to the synthesis of Cu/CuO-NPs were investigated.

Extracting copper from copper oxide ore by a zwitterionic

04.03.2015 · Sulfamic acid (SA), which possesses a zwitterionic structure, was applied as a leaching reagent for the first time for extracting copper from copper oxide ore. The effects of reaction time, temperature, particle size, reagent concentration, and stirring speed on this leaching were studied. The dissolution kinetics of malachite was illustrated with a three-dimensional diffusion model.
