A molybdenum sulfide ore inhibitor, a copper-molybdenum sulfide ore flotation separation method and application

Abstract

This invention relates to the field of mineral processing technology, and particularly to a depressant for molybdenum sulfide ore and a flotation separation method and application for copper-molybdenum sulfide minerals. The depressant comprises polyphenols; the polyphenols have the molecular formula C0.05. 32 H 30 O 11 The molecular weight is 590.57 g / mol, and the degree of polymerization is 2-11. The molybdenum sulfide mineral depressant is used for the flotation of copper-molybdenum sulfide minerals. The copper-molybdenum sulfide minerals contain chalcopyrite and molybdenite, with a mass ratio of 1-2:1. This invention provides a molybdenum sulfide mineral depressant and a flotation separation method and application for copper-molybdenum sulfide minerals. The aim is to solve the problems of high toxicity, high loss rate, and high intermingling of existing copper-molybdenum sulfide mineral separation flotation depressants, and to achieve effective separation of chalcopyrite and molybdenite.
