老挝铝土矿中铁矿物微观结构及反应特性的研究仓向辉1(1.河南省郑州市铝业股份有限公司郑州研究院)摘 要:利用扫描电镜及能谱仪对铝土矿中铁矿物微观结构及成分进行分析,着重研究铝土矿中赤铁矿,针铁矿,钛铁矿等矿物的存在方式及分布特征.结果表明,针铁矿较多时明显影响赤泥的沉降速度,碳加入量大于10%及高温溶出能显著改善老挝矿的溶出效果,赤铁矿不与矿石中各组分和铝酸的溶液反应而直接进入赤泥中.关键词:微观结构； 铁矿物； 反应特性； 铝土矿......
-utilization incorporated to alumina extraction is meaningful to directly decrease the red mud discharge. Several alumina refineries for treating diasporic bauxite in China adopt high-gradient magnetic... was proposed to treat diasporic bauxite by adding iron powder (1-4 wt.% of bauxite) instead of lime (10-13 wt.% of bauxite). From the previous report [19], a qualified iron concentrate (TFe>56......

depressant 1 Introduction China has abundant bauxite ore resources, however, more than 98% of the bauxite ores are the diasporic type with the characteristics of complex mineral composition, low A/S (mass ratio of Al2O3 to SiO2) and difficulty to process. For diasporic bauxite with A/S less than 8, a sintering process or a combination of sintering and Bayer process can be used [1]. However......
