Reexamining the role of ammonium ions in the sulfidization, xanthate-flotation of malachite

from Minerals

Reexamining the role of ammonium ions in the sulfidization, xanthate-flotation of malachite Minerals Ammonium ions have positive effects on the sulfidization flotation of malachite; however, the underlying mechanisms remain poorly understood. In the present work, micro-flotation tests, field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and solution analysis for ammonium nitrogen were carried out.
