| Abstract: | Through roughing once, scavenging once and selecting once of flotation processes, the gold and silver is recovered with inhibiting zinc floating gold-silver technology. The experimental research indicates that gold-silver concentrate is20.96g/t in gold grade, 1807.38g/t in silver grade, 90.35% in gold recovery, 93.79% in silver recovery, zinc concentrate is 53.97% in zinc grade, 98.97% in zinc recovery. Results show that the grade of zinc-concentrate gained from flotation test can be raised 10% respectively. The separation technology achieves comprehensive recovery of valuable elements such as gold and silver, meanwhile zinc-concentrate quality is improved greatly. |
