中文摘要: 以铌矿为原料直接制备出铌镍合金粉前驱体NiNbO6,考察了硫酸焙烧阶段磨矿粒度、焙烧温度、焙烧时间、酸矿比、硫酸浓度对铌浸出率的影响。结果表明,最佳硫酸焙烧工艺参数为:磨矿粒度-0.025 mm、焙烧温度300 ℃、焙烧时间3 h、硫酸浓度10mol/L、酸矿比2.5,在此条件下,铌浸出率可达到94%以上,回收率达到93%。
Abstract:Niobium-nickel alloy powder precursor NiNbO6 was prepared directly from niobium ore. Effects of grinding size, roasting temperature, roasting time, ratio of acid to ore, and sulfuric acid concentration on niobium leaching rate during sulfuric acid roasting were investigated. The results show that niobium leaching rate is 94% above with niobium recovery of 93% under the optimum conditions including grinding size of -0.025 mm, roasting temperature of 300 ℃, roasting time of 3 h, ratio of acid to ore of 2.5, and sulfuric acid concentration of 10 mol/L.
