| Abstract: |
| Since In Dulong Zinc-Tin polymetallic ore, since the cassingite has fine grain size and high mud content, so which belongs to the resources of difficult to recover. In order to improve the comprehensive utilization rate of fine-grain cassiterite resources, this experiment used a process of desilting-flotation and the high efficient inhibitor OL-1C, which significantly changed the the flotability of magnesia gangue and sludge in the feeding, reduced their chance of entering the concentrate, and strikingly improved the grade and recovery rate of cassiterite flotation concentrate . By adding the high-efficiency inhibitor OL-1C with 20g/t, the grade and recovery of Sn increased by 2.54% and 0.74% in concentrate respectively. |
