| 摘 要： | 在对高炉瓦斯泥性质、矿物成分分析的基础上,采用选冶联合技术对其有价元素进行了提取研究。试验研究表明,瓦斯泥原料经摇床分选后,获得了铁品位为53.25%,回收率为51.05%的铁精矿;摇床尾矿经浮选柱一次粗选两次精选工艺流程,得到碳品位为74.21%、作业回收率为66.39%的碳精矿;最终尾矿采用硫酸进行浸锌试验,锌的浸出率可达97.85%,向浸出液中加入硫化钠用量为200kg/t时,Zn回收率达到86.36%。

| Abstract: | After analyzing the properties, chemical composition of the flue slime from the blast furnace in Tangshan Iron Steel Company, the paper proposed the suggestion of recovering valuable elements from flue slime by combining process of mineral processing and metallurgy. The laboratory test results showed that the iron concentrate with the iron grade 53.25% and recovery of 51.05% by tabling gravity separation as well as the carbon concentrate with fixed carbon content of 74.21% and recovery of 66.39% by once rough separation and two times cleaning separation were obtained. The addition of sulfuric acidSto the finalSflotation tailings,Sthe leaching rate of zincSis 97.85%.When the dosage of sodium sulfide is 200kg/t,the recovery of zinc concentrate can reach to 86.36%. |
