The Erdenet tailing storage facility (TSF) is one of the largest in the world with a total area of 18.6km2. Over 40 years of history of Erdenet mining, the process tailing has been collected in the tailing dam and now becomes the biggest resource for research. The goal of this research work is to define the optimized condition of the flotation with the highest achievement of Cu recovery from the tailings of the Erdenet Copper Mining (EMC). Series of research and laboratory experimental works including physical and chemical characterization of the tailing samples, flotation experiments and analysis were carried out in order to define the optimized condition of the flotation. The best recovery of tailing sample with 0.1% of Cu was 1.4% of Cu grade and 32.27% of cumulative recovery.
