A flotation experimental study was conducted to process a copper sulfide ore. A closed-circuit flowsheet consisting of copper preferential flotation and sulfur recovering from copper flotation tailings was adopted, resulting in a copper concentrate grading 23.01% Cu at 95.47% recovery and a sulfur concentrate grading 35.72% S at 58.48% recovery.
