Abstract: In order to make an effective recovery of such valuable elements as copper, sulfur and iron etc. from tailings of Nanjing Iron & Steel Company, the flotation tests on these tailings are made. Good comprehensive recovery index are obtained, including copper concentrate with copper grade of 10.31% and recovery of 46.44%, sulfur concentrate with sulfur grade of 37.46% and recovery of 75.43%, and iron concentrate with Fe grade of 65.72% and recovery of 13.28%.
