【摘要】 对某铅锌矿深部矿体的多种矿样进行了选矿试验研究。结果表明 ,采用同一工艺流程可处理各种氧化率不同的矿石 ,当矿石氧化率变化时 ,仅需对氧化物浮选硫化钠及胺的用量稍作调整 ,即可取得好的选别指标。该工艺实现了不脱泥浮选氧化锌矿物更多还原

【Abstract】 Beneficiation tests were made on various samples of the deep orebody of a lead-zinc mine. The results show that ores with different oxidabilities can be beneficiated by a same process circuit. When the oxidability of ores varies, good beneficiation indexes can be also obtained by slightly adjusting the dosage of sodium sulphide and amine in the floatation mineral oxides. Using the process can realize the floatation of zinc oxide ores undeslimed.更多还原
