摘要
根据河北省丰宁银矿银矿石的性质及现场生产情况 ,重点研究了磨矿细度、矿浆pH值、浮选药剂制度等条件及不同的磨浮工艺流程对选银回收率的影响。试验研究结果表明 :选用丁基黄药和戊基黄药适宜比例 (为 1∶3)及 95 38硫化矿物捕收增效剂来强化银的浮选 ,采用阶段磨浮工艺流程 ,可获得银回收率为 94 .32 %的理想指标。
The influences of grinding fineness,pH value of pulp,flotation reagent and different process flow of flotation technology on silver recovery rate were studied.It showed that by using mixed reagent (butyl xanthate/penty1 xanthate ratio was 1∶3)and 9538 collector for sulfide mineral to intensify silver flotation and by adopting the process flow of stage grinding-flotation,the silver recovery rate reached 94.32%.
