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3h、水浸液固比7∶1、水浸温度70℃、水浸时间2.5h的条件下,浸出效果最好,浸出液中镍浸出率达到73.43%。
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 3h,ratio of solid to liquid of 7∶1,leaching temperature of 70℃,and leaching time of 2.5h.
