| Abstract: |
| According to the characteristics of a sulfur ore of low grade cooper ore in Yunnan province, adopting preferential flotation of cooper ore dressing experiment process. Test conditions on grinding fineness was 80% -0.074mm cases adopted once roughing twice cleaning third scavenging preferential flotation of cooper process, sulfur circuit also adopted once roughing twice cleaning third scavenging float sulfur process .Through closed-circuit test was ultimately for beneficiation indicators: cooper concentrate with cooper grade of 20.31%,recovery of 80.46%; and sulfur concentrate with sulfur grade of 45.3%, recovery of 90.35; gold and silver at the same time also had a certain degree of enrichment. |
