, 2007 利用摇瓶浸出研究了氧化亚铁硫杆菌在35℃下生物浸出铁闪锌矿的过程,探讨了铁含量和细菌接种量等因素对细菌在矿浆中的生长以及对锌浸出的影响,并对细菌浸出铁闪锌矿的机理进行了分析.发现在不添加铁的情况下,即使细菌接种量达到40mL,矿浆的氧化还原电位提高仍然非常缓慢,细菌无法在矿浆中正常生长,证明不存在直接浸出;而在添加FeSO4-7H2O的矿浆中,随接种量的增加细菌浸出铁闪锌矿的速度加快.结果表明,铁闪锌矿的浸出需要一定量的Fe3+作为氧化浸出剂以提高浸出速度,因此必须预先添加部分Fe2 ...

, 1988 本文研究叔胺从硫酸铝溶液中萃取除铁新工艺。进行了广泛的条件实验,表明添加剂,胺种类,水相pH,铁—铝比,接触时间、温度等对铁的萃取及铁—铝分离均产生影响。研究了负铁有机相的反萃行为。采用稀硫酸,只要保持反萃后液pH～1.0,便可以获得满意的反萃效果。使用水多级错流,也可以有效地反萃铁。利用铝土矿硫酸浸出液进行了串级流动试验。取得了除铁率>99%,硫酸铝溶液中剩杂铁量5×10~3的满意结果。本工艺采用廉价的工业萃取剂7301(即N235)萃铁,反萃剂硫酸用量较文献中报导的许多体系降低10—20倍 ...

, 1986 采用转移弧等离子冶金炉熔态还原钛铁矿的试验研究表明,由钛铁精矿与煤粉制成的压块,若碳的含量为氧化铁还原所需的90～100%时,它有很高的还原速率,同时渣中 FeO 的含量低于3.5%。在开发新流程时 ...
