| 摘 要： | 将尾矿水回用于浮选过程中已成为当今选矿废水治理的普遍趋势。对于多次循环利用后的选矿废水,其中累积的药剂及无机离子会达到一定浓度。为了研究高浓度无机离子对矿物可浮性的影响,以会泽铅锌矿方铅矿、闪锌矿和黄铁矿为研究对象,分别在三种单矿物的浮选过程中加入大量的Ca2+、Mg2+和SO42-,通过回收率变化研究其对可浮性的影响,并通过分光光度仪、SEM等仪器对其影响机理进行分析。试验结果表明当加入的Ca2+、Mg2+和SO42-达到特定浓度后,对三种矿物的可浮性将会有不同程度的影响。

| Abstract: | It has become a trend that the tailings water is recycled to floatation in the treatment of flotation wastewater.The drugs and inorganic ions are aggregated to a high concentration in the floatation wastewater after several recycle treatment.In order to study the influence to the floatation of the inorganic ions in high concentration,it was discussed through the various recovery and analyzed by using some devices like spectrophotometer,SEM and so on,when lots of Ca2+,Mg2+ and SO42-were added to the floatation water of the three pure minerals which are the galena,sphalerite and pyrite from Huize Lead-Zinc Ore.The recovery of three minerals will fall in some different extent when the concentrations of Ca2+,Mg2+ and SO42-reach a critical value. |
