Mineral processing tests were conducted for a fine refractory copper ore with Cu grade of 0.75%. A combined process consisting of magnetic separation, rapid flotation of copper minerals, enhanced copper flotation of rapid flotation tailings, and regrinding and cleaning of rough copper concentrate was adopted in a closed-circuit test, yielding a copper concentrate grading of 23.57% Cu at a recovery of 83.23%.
