DOI: 10.1016/j.jiec.2016.09.040
Abstract: Abstract Density functional theory calculations, flotation behavior, X-ray photoelectron spectroscopy, and infrared spectra were combined to reveal the Cu2+ activation mechanism on a cyanide (CN−)-leached sphalerite surface. Low CN− adsorption enhanced the activation capability of… read more here.
