Study on Technological Mineralogy of a Certain Lead-Zinc Ore

摘要

The characteristics of process mineralogy of the some lead-zinc mine were studied with scanning electron microscope, optics microscopes, and x-ray diffraction. The species of lead minerals and zinc minerals and the chemical composition of the minerals were analyzed. The liberations at different grinding finenesses and the particle sizes of the minerals had been also determined. The phase shape of lead and zinc in the ore was also analyzed. The behaviors of various minerals and mineralogical factors affecting the flotation had been explained clearly. The investigation results were favorable to reasonable selection of flotation parameters and would provide theoretical guidance to lead-zinc separation.
