铬铁矿硫酸酸解过程强化

, 2016
针对铬铁矿硫酸酸解条件苛刻的难题,提出机械活化和氧化剂相结合强化铬铁矿硫酸酸解过程的新方法.以南非铬铁矿为原料,考察了液固比、硫酸浓度、机械活化、氧化剂加入量、温度等参数对铬浸出过程的影响,对铬铁矿硫酸酸解过程铬的浸出动力学进行了研究.结果表明,最佳浸出条件为:液固比2.4 m L/g,硫酸浓度80%(?),机械活化时间20 min,氧化剂加入量13%(?),温度120℃,浸出时间5 h,该条件下铬浸出率达92.36%.浸出过程符合未反应收缩核模型.

酸性溶液中磁黄铁矿在氧压下的水相氧化

, 1988
本工作以氧分压、初始酸度、温度和原料组成为变量,研究了两种含镍磁黄铁矿精矿对酸性氧压浸出工艺的响应。发现在研究条件下磁黄铁矿的水相氧化十分迅速、完全,而铜镍的浸出则随反应条件波动较大,在适当条件下也可浸出相当完全。讨论了镍铜浸出与磁黄铁矿水相氧化的关系。指出可在0.6MPa 氧压、130℃的温和条件下充分氧化磁黄铁矿 ...
