Abstract: Inner Mongolia Huogeqi is a polymetallic deposit and main element is copper.The mine has contact metasomatic type deposit characteristics,1.10% Cu.Through the analysis of ore chemical composition, mineral composition and occurrence mode, the structure of main minerals,monomer dissociation, disseminated extent and characteristics were understood, find out the mineralogy factors influencing copper recovery rate.Process of copper priority flotation-copper tailings magnetic separation to comprehensive recovery pyrite was recommended, results can provide technical basis for the development and utilization of the mineral resources.
