Comprehensive utilization of tailings is a necessary way to build a green tailings-free mine. Faced with the progress of technology, the policy change and market uncertainty, comprehensive utilization facilities and filling system of tailings should have certain adaptability. According to the actual situation of a mine, the tailings produced by the concentrator of the mine are categorized into unclassified tailings, classified fine tailings and classified coarse tailings. Through experimental research and theoretical calculation, the total tailings amount, fine tailings amount and operating cost consumed by different tailings as filling materials are analyzed. On this basis, the optimized design and key equipment of the filling system are studied, and the optimal filling processes which can adapt to various filling conditions such as unclassified tailings filling, classified coarse tailings filling and classified fine tailings filling are put forward.
