【摘要】 在不同溶出温度、时间、碱浓度、预脱硅时间、石灰添加量等条件下,研究了石灰活性对—水硬铝石型铝土矿拜耳法溶出的影响。研究发现,在钢弹反应器中或管道—停留罐反应器中,石灰活性的影响都是很大的。溶出条件愈差,这种影响愈大。更多还原

【Abstract】 In the Bayer process, the effect of lime activity on digesting diasporic bauxites was studied at various digesting temperature, time, concentration of caustic soda, predesilication time and lime dosage, etc.Experiment results demonstrated that the lime activity had an obvious influence on dissolving alumina from bauxite in either the steel-bomb reactor or the tube-autoclave digester.The worse the digesting condition, the more obvious the influence.更多还原
