RESEARCH ON WET DETOXIFICATION TECHNOLOGY OF CHROMITE ORE PROCESSING RESIDUE

  • 摘要: 以治理铬渣中的Cr(Ⅵ)污染为目的,提出了硫酸浸出-硫酸亚铁还原的铬渣湿法解毒工艺,在对铬渣处理前后的表面形貌进行表征的基础上,探究了不同处理条件下铬渣中Cr(Ⅵ)的处理效果及其修复机理。结果表明:铬渣湿法球磨时间为20 min时,铬渣颗粒98.68%过200目筛,水溶性Cr(Ⅵ)的浸出率可达40.96%;铬渣硫酸添加量为60%,液固比为4∶1,酸溶时间为2.5 h时,Cr(Ⅵ)浸出趋于饱和,此时浸出终点pH为5.8,水溶性和酸溶性Cr(Ⅵ)总浸出率为95.38%;硫酸亚铁添加量为40%时,铬渣中Cr(Ⅵ)含量下降为1.38 mg/kg。铬渣中Cr(Ⅵ)的去除主要与硫酸对含Cr(Ⅵ)矿物的溶解、SO42-和CrO42-的离子交换以及Fe(Ⅱ)对溶液中Cr(Ⅵ)的还原作用有关。
