Flotation Separation of High Sulfur Lead-Zinc Ore

Abstract:

According to the refractory lead-zinc ore properties with high pyrite, the experimental studies were conducted on floatation reagent conditions and closed circuit tests for comprehensive recovering of all types useful minerals. In comparison to the test results of different process flowsheets and different types of flotation reagents, adopting prior flotation lead (Pb)—Zn selective flotation (reagent removal and regrinding of rough concentrate)—S-selective flotation with Zn-tailings. The closed circuit tests were achieved: the grade of lead concentrate was 50.55% with a recovery of 92.25%; The grade of zinc concentrate was 40.12% with a recovery of 85.82%; The grade of sulfur was 48.58% with a recovery of 56.59%; The tailings grades of lead, zinc and sulfur were 0.27%, 0.31%, 3.90% respectively.
