摘　　要：为提锂铷冶金尾渣制备硅肥试验研究表明:提锂铷尾渣采用配碱高温改性制备硅肥,有效硅活化效果良好。提锂铷尾渣制备硅肥优化的硅肥改性参数为:碱配比10%,焙烧温度850~950℃,焙烧时间60~90min,改性硅肥有效硅可达20%以上。合成浸渣硅肥满足国家标准硅肥(NY/T 797-2004)的各项指标要求。锂铷矿石资源有望实现全相回收。Silicate fertilizer preparation by leaching residues of Li-Rb bearing ore was investigated. The results showthat： alkali baking preocess is feasible. The optimized parameters of silicon fertilizer were as follows： alkali ratio of 10%, calcination temperature of 850 - 950 ℃ , calcination time of 60 - 90min.Synthetic silicate fertilizer could meetthe indicators of national standard silicon fertilizer （NY / T 797-2004）. Comprehensive utilization of Lithiumrubidiumbearing resources would be improved.
