  • 云南某异极矿氧化锌矿石选矿试验研究……焦科诚
  • 摘 要:云南某异极矿氧化锌矿石属于氧化程度较高的难选氧化锌矿石,锌质量分数8.31 %。针对该矿石性质,进行了硫化-组合用药浮选工艺流程条件试验。结果表明:在磨矿细度-0.074mm 80 %及其他最佳参数条件下,浮选闭路试验可获得锌质量分数30.11%、锌回收率75.27%的锌精矿,硫化-组合用药浮选工艺流程合理、稳定性好。

    Experimental study on the processing of a heterogeneous zinc oxide from Yunnan……Jiao Kecheng

    AbstractA heterogeneous zinc oxide from Yunnan is refractory with high oxidationlevel,and the mass fraction of zinc is 8.31 %.According to the ore property,asulfuration-combined agent flotation process is conducted for the condition experiment.The results show that when the grinding fineness of -0.074 mm accounts for 80 % and other parameters are optimal,the closed flotation circuitcan obtain the zinc mass fraction of 30.11 % and the zinc concentrates with the recovery of 75.27 %.The sulfuration-combined agent flotation process is reasonable in flow sheet and good in stability.

    Keywords:zinc oxide ore; heterogeneous ore; sulfuration; reagent combination; flotation
