The current status quo of the existing metal and chemical non-metallic mines in Nanjing is statistically analyzed, and the economic potential of different mines is evaluated. This paper mainly analyzes and discusses the economic value and environmental benefits of comprehensive utilization of co-occurring minerals and tailings in metal mines. The comprehensive utilization of co-occurrence minerals can refine a variety of useful elements with high selectivity and smelting value and significant economic benefits, or as building materials, and more importantly, can solve the problem of tailings piling up Environmental pollution and occupy land and other huge pollution problems. Finally, it analyzes the unfavorable factors that affect the comprehensive utilization of Nanjing mining enterprises.
