Abstract: A selected iron tailing contains 0.031% molybdenum.In order to effectively recover its valuable metals, flotation experiments are carried out on the basis of process mineralogy.The results show that the test uses a crude concentrate regrind process, and a roughing, seven scavenging, three cleaning of experiments are obtained to obtain a molybdenum concentrate containing 0.75% zinc, 0.42% zinc recovery, 46.11% molybdenum and 67.49% molybdenum recovery.
