The process mineralogy of polymetallic low-grade tailings of Liwu copper ore was investigated by chemical methods and microscopic observation.The results show that the major metallic minerals consist of pyrrhotite,chalcopyrite and marmatite.The major gangue minerals are quartz,chlorite,and plagioclase.The content of the coarse tailings of +0.097 mm is 63.2%,the copper content of the tailings of -0.200~0.074 mm is 57.12% of total copper,Znic content of the tailings of -0.200~+0.074 mm is 66.70% of total Znic.The distribution rates of the fine-disseminated gold and silver had a positive correlation with the distribution rate of copper.It was difficult for pyrrhotite,chalcopyrite and marmatite to liberate fully due to their complex intergrowth relationship.Compared to flotation,it is cost-effective that biohydrometallurgy is used to recover copper and znic from Liwu copper ore tailings.
