Abstract

Abstract:

The raw ore of a carlin gold mine in Guizhou has low gold grade，fine disseminated granularity of valuable minerals and gangue minerals，and high content of harmful elements arsenic and carbon.The recovery rate of conventional fine grinding flotation process is only 80.54% and the gold grade of tailing is 0.97×10^-6，the loss of flotation tailing gold is relatively serious.In order to improve the recovery rate of gold concentrate and reduce the gold grade of flotation tailing，the process mineralogy study of secondary grinding classification overflow and flotation tailing was carried out to find out the gold distribution and loss.The results show that the gold lost in conventional fine grinding flotation tailing is mainly sulfide wrapped gold，which is mainly lost in the poor coenobium of -38 μm grade，accounting for 60.70%，and the lost sulfide gold content is high.Secondly，there are a small amount of dissociated monomer and a small amount of fusant，which are not fully recovered due to the fine particle size，and also lost in the tailings.The main cause of the loss of gold in flotation tailing is that the fine particle minerals cannot be caught by conventional fine grinding flotation.Combined with the site production situation，the JRF micro-bubble flotation was applied to rough selection Ⅰ operation and scavenge Ⅳ tailing for reselection test.The test results show that JRF micro-bubble flotation has a significant catching effect on some fine particle minerals in tailing，which can further strengthen the capture of sulfide poor coenobium of -38 μm grade and a amount dissociation monomer of -20 μm grade in conventional fine grinding flotation scavenge Ⅳ tailing，and reduce the loss of gold in flotation tailing.After the technical transformation，the cumulative recovery rate of gold is 82.39% and the tailing grade is 0.88×10^-6.The recovery rate increased by 1.85 percentage points，and the tailing grade decreased by 0.09×10^-6，and the flotation index was gradually improved，which increased the economic benefits of enterprises.

Key words: gold, process mineralogy, JRF micro-bubble flotation, flotation tailing, recovery, fine particles
