中文摘要: 采用硫酸化焙烧再水浸的方法从钙镁磷肥的副产物镍磷铁中提取镍,重点研究了提镍过程中相关因素对镍浸出率的影响。结果表明,在酸料比0.5、焙烧温度300 ℃、焙烧时间3 h、水浸液固比7∶1、水浸温度70 ℃、水浸时间2.5 h的条件下,浸出效果最好,浸出液中镍浸出率达到73.43%。
Abstract:Nickel was extracted from nickel ferrophosphorus, by-product of calcium-magnesium phosphate (fertilizer), with atmospheric pressure sulfating roasting and water leaching process. The effects of technical parameters on nickel leaching rate were emphatically investigated. The results show that the nickel extraction rate is 73.43% under the optimum conditions including ratio of acid to material of 0.5, roasting temperature of 300 ℃, roasting time of 3 h, ratio of solid to liquid of 7∶1, leaching temperature of 70 ℃, and leaching time of 2.5 h.
