摘要
某铜锌矿选厂浮选尾矿中含有少量可综合回收的锂铷矿物,其中Li2O和Rb2O的含量分别为0.337％和0.109％.因尾矿石中泥化脉石矿物含量较高,采用常用锂矿捕收剂难以有效富集,选别难度较大.采用"擦洗脱药-脱泥-选锂-中矿再选"的选矿新工艺和新型高效锂云母捕收剂CK-L,获得了 Li2O品位为1.64％、Rb2O品位为0.39％的锂铷精矿,Li2O回收率为64.02％,Rb2O回收率为48.69％,获得了较好的选矿指标,有效回收了铜锌尾矿中的锂铷资源,提高了资源综合利用率.
Abstract
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.
