| Abstract: | Comprehensive recovering of ultra-lean copper and sulfur minerals associated in an iron ore from Hubei province was investigated. A closed-circuit test, adopting a flowsheet consisting of Cu-S bulk flotation, Cu-S separation, and merged middlings desliming, produced a copper concentrate approaching 16.55% Cu grade at 67.31% recovery with a yield of 0.08%, and a sulfur concentrate at 49.10% S grade at 62.51% recovery with a yield of 7.06%. New economic and social benefits can be generated from the comprehensive recovery of copper and sulfur. |
