The results of an experimental study into the reduction smelting of rhenium-containing cyclone dust obtained from lead production are presented. The optimal dust processing modes characterized by the extraction of water-soluble rhenium (80–84.3%) and water-insoluble arsenic compounds (65–70%) into sodium sulfate slag are established. Thermogravimetric studies were carried out to establish the partial transition mechanism of rhenium and arsenic into sublimates during the reduction smelting process. The unfavorable transition of rhenium and arsenic to sublimates was shown to occur prior to the onset of coke ignition and formation of sodium sulfate melt.

后处理工艺铅生产原料提取铼和砷的方法开发

介绍了对从铅生产中获得的含铼旋风粉尘进行还原冶炼的实验研究结果。建立了以将水溶性铼(80-84.3%)和水不溶性砷化合物(65-70%)提取到硫酸钠渣中为特征的最佳粉尘处理模式。进行了热重研究,以建立在还原冶炼过程中铼和砷向升华物的部分转变机制。铼和砷向升华物的不利转变显示在焦炭点燃开始和硫酸钠熔体形成之前发生。
