由高铁低锌萃铟废水制备锌精矿和铁红
Guocheng Gongcheng Xuebao/The Chinese Journal of Process Engineering（2010）
Abstract
控制pH值,对高铁低锌萃铟废水加入硫精矿直接制备锌精矿和铁红进行了研究.分析了反应机理,考察了不同硫化物对锌的回收效果,探讨了超声波辅助硫精矿制备锌精矿和高纯铁红的工艺条件,并利用SEM对锌精矿粒度和形貌进行表征.在萃铟废水中含铁60.47 g/L、锌28.65 g/L时,在常温下调节pH值为2,加入-0.074 mm硫精矿,超声处理50 min的实验条件下,制得了含锌50.36%的锌精矿产品,锌回收率达95.29%,锌含量和回收率分别比未经超声处理提高了18.52%和23.67%.制得的高纯铁红符合国家SJ/T10383-93标准一等品的要求,铁回收率为92%.
