| 1 | 从勃姆石−高岭石型高硅铝土矿中盐酸浸出铁的机理与动力学显示文摘利用XRD、ICP-OES、TG/DSC、SEM、TEM和穆斯堡尔(Mössbauer)光谱研究来自俄罗斯阿尔汉格尔斯克地区Severoonezhsk铝矿中铝土矿的化学和矿物组成,发现该铝土矿的含铁矿物包括铝针铁矿(α-Fe_(1−x)Al_(x)OOH)、铝赤铁矿(α-(Fe_(1−x)Al_(x))_(2)O_(3))、正方铝针铁矿(β-Fe_(1−x)Al_(x)O(OH,Cl))和铬铁矿(FeCr_(2)O_(4))。在温度为100℃、HCl浓度为10%,固液比为1:10及浸出时间为60 min的条件下,盐酸浸出铝土矿的铁浸出率为82.5%,而铝的损失不到铝土矿中总铝含量的4.5%。铁浸出过程的动力学分析表明,温度为90~100℃时,扩散是浸出过程的速率限制环节。铝土矿浸出渣含有微量的α-Fe_(1−x)Al_(x)OOH和β-Fe_(1−x)Al_(x)O(OH,Cl),大部分铁呈FeCr_(2)O_(4)形态。除铁氧化物外,铝土矿盐酸浸出渣中铬和钙氧化物的含量也显著降低。含氯化铁的浸出液含有稀土元素(REE):6.8 mg/L Sc、4.1 mg/L Ce和2.3 mg/L Ga。 | Dmitry VALEEV Denis PANKRATOV Andrei SHOPPERT Artem SOKOLOV Alexandr KASIKOV Alexandra MIKHAILOVA Cristian SALAZAR-CONCHA Ilia RODIONOV | 2021 | Transactions of Nonferrous Metals Society of China2021，31，10： | 4 |
