采用电化学技术研究了孟加拉国海沙里钛铁矿在硫酸溶液中不同温度下的溶解行为.循环伏安研究表明,在没有添加碳粉的条件下钛铁矿的溶解非常困难.为探明钛铁矿的溶解过程,考察了钛铁矿-碳比例、硫酸浓度和温度对钛铁矿电化学溶解行为的影响.结果显示,钛铁矿在低还原电位和低温下的溶解速率较慢.施加更负的还原电位和在较高的温度下溶解速率加快.增加硫酸浓度(最大浓度达到1 m.l·L^(-1))也可提高溶解速率,但在较高的硫酸浓度和还原电位下,由于氢气析出导致钛铁矿的溶解速率降低且气体吸附,最后使得钛铁矿的活性表面积减小.计算得到活化能数值在高温区间为50±10 k.·m.l^(-1),而低温区间为~15±5 k.·m.l^(-1),说明低温区间为扩散控制过程,而高温区间为化学控制过程.
