摘要
采用硫酸浸出工艺从镍磷铁中浸出镍,考察温度、固液比、硫酸质量分数和浸出时间对浸出过程的影响。研究结果表明,在温度为80℃,固液比为1∶10,硫酸质量分数为40%和加入少量过氧化氢浸出12 h时,镍磷铁中镍和磷的浸出率分别为91.0%、85.9%。
Sulfuric acid leaching process is used to extract nickel from the nickel-phosphorus iron.The influences of emperature,solid-liquid ratio,concentration of immersion and leaching time on leaching process are studied.The results show that the leaching rate of nickel and phosphorus of nickel-phosphorus iron can reach 91.0％ and 85.9％ respectively,under the following conditions：80℃ of temperature,1∶10 of solid-liquid ratio,40％ mass fraction of sulfuric acid,a small amount of hydrogen peroxide and 12 hours of Ieaching time.
