, 2013 为了高效开发利用某高镁铜尾矿中的镁,对其盐酸浸取工艺技术条件进行了研究,并建立了浸出动力学模型。研究结果表明,在盐酸浓度为1 mol/L,反应温度为353 K,液固比为3∶1,反应时间为4 h,搅拌速度为300 r/min条件下,镁浸出率可达75.55%;Avrami模型能较好地描述浸出过程。对不同条件下浸渣的XRD、SEM分析表明:当镁浸出率为75.55%时,蛇纹石结构基本全部被破坏,因而浸渣中的蛇纹石衍射峰消失;高温高压也仅能使部分钙镁榴石晶体结构不稳定,并与盐酸反应 ...

, 2009 研究了由MgSO4和Na2CO3在283~363K反应沉淀得到的碳酸镁水合物的组成和形貌随反应温度的变化规律,并对产品进行了表征.结果表明,在283~313K间,可得到棒状三水碳酸镁(MgCO3-3H2O);当温度升高到323K时,产物由棒状三水碳酸镁变为球形碱式碳酸镁,且随着反应温度升高,球形碱式碳酸镁的直径增大 ...
