铜钼分离技术研究现状与展望OA

Copper and molybdenum are important non-ferrous metals,which are often associated in porphyry copper deposits.Chalcopyrite and molybdenite are closely associated with each other,and their floatability is similar,resul-ting in difficulty in flotation separation of copper and molybdenum.This paper briefly analyzes the current situation of copper-molybdenum ore resources,and introduces in detail the research status of three commonly used copper-molyb-denum separation technologies:preferential flotation,iso-flotation and mixed-separation flotation.Inhibitors are the key to the separation of copper and molybdenum.The research progress of chalcopyrite inhibitors and molybdenite inhibitors is summarized.In the future,we should vigorously develop new combination inhibitors with high efficiency,economy and environmental protection,and make full use of the synergy between inhibitors in order to obtain better selective inhibition effect.
