| Abstract: |
| The quartz vein type gold ore from Hebei Chengde contains 10.4g/t gold. Pyrite is the main gold-bearing mineral, and the dissemination size of gold is different. It is confirmed that the ore is suitable to adopt single flotation process through exploration test. The results of beneficiation test show that: with the grinding fineness is 59.44%-0.074mm, sodium carbonate as pH regulator and butyl xanthate as collector, the gold concentrate with gold grade 179.21g/t, gold recovery 96.47% and the tailings with gold grade 0.39g/t were obtained through one stage of roughing, one stage of cleaning and two stages of scavenging. The process realized the high efficiency utilization of the gold resource. |
