Experimental Study on Comprehensive Recovery of Lithium and Rubidium from Copper-Zinc Flotation Tailings
The flotation tailings of a copper-zinc ore dressing plant contain a small amount of lithium and rubidium minerals that can be comprehensively recovered,with Li2O and Rb2O contents of 0.337％and 0.109％,respectively.Due to the high content of argillized gangue minerals in tailings,it was difficult to enrich effectively using common lithium ore collectors,which making the separation process challenging.A new beneficiation process of scrubbing,desliming,lithium selection,and intermediate ore re-separation and a new high-efficiency lithium mica collector CK-L were used to obtain a lithium and rubidium concentrate with a Li2O grade of 1.64％and a Rb2O grade of 0.39％.The recovery of Li2O was 64.02％and the recovery of Rb2O was 48.69％.Good beneficiation indexes were obtained,which effectively recovered the lithium and rubidium resources in copper-zinc tailings and improved the comprehensive utilization rate of resources.
