中文摘要: 对高浓度熟料溶出过程影响因素进行了详细研究。结果表明:高浓度熟料溶出时,对溶出过程影响较大的因素主要是液固比、溶出温度、溶出时间、调整液Al2O3浓度及SiO2浓度;高浓度熟料溶出时,碳酸钠浓度和游离苛性碱浓度对溶出液SiO2浓度和Al2O3溶出率的影响不大,相对调整液Al2O3浓度而言,是次要作用,这与低浓度溶出过程大多数研究结论有所不同;高浓度熟料溶出时,硫钠浓度对溶出过程影响极小;高浓度熟料溶出时,控制好溶出过程主要影响参数,可将溶出过程二次反应控制至最低。
Abstract:The factors in the process of high concentration sinter leaching were studied in detail. The results indicate that factors which have profound influence on the SiO2 and Al2O3 concentration of pregnant liquor are mainly the ratio of liquor to solid, temperature, time, alumina concentration as well as SiO2 concentration during the high concentration leaching. However, sodium carbonate and free caustic alkali concentration as well as sodium sulfate have no remarkable effect on it, comparing alumina concentration, they are the secondary factors. Secondary reaction may reduce to a lower level after making the major effect param- eters of the process of the high concentration leaching under control.
