Secondary reaction mechanism of leaching process of calcium aluminate slag 作者:Sun, HL (Sun, Hui-lan)[ 1,2 ] ; Wang, B (Wang, Bo)[ 1,2 ] ; Zhang, JX (Zhang, Jian-xin)[ 1 ] ; Zong, SF (Zong, Shu-feng)[ 1 ] ; Liu, JJ (Liu, Jia-jia)[ 1 ] TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA 卷: 25 期: 4 页: 1334-1340 DOI: 10.1016/S1003-6326(15)63732-3 出版年: APR 2015 查看期刊信息 摘要 SiO2 in calcium aluminate slag exists in the form of gamma-2CaO center dot SiO2 which is more stable than beta-2CaO center dot SiO2. However, it is decomposed by sodium carbonate solution during leaching process, leading to the secondary reaction. The extent of secondary reaction and reaction mechanism of calcium aluminate slag were studied using XRD. The results show that the decomposition rate of gamma-2CaO center dot SiO2 increases with the increase in leaching time and sodium carbonate concentration. The main products of secondary reaction are the mixture of hydrogarnet and sodium hydrate alumina silicate. SiO2 concentration rises firstly and then drops with the increase of leaching temperature. XRD results indicate that the stable product of secondary reaction at low temperature is hydrogarnet. But hydrogarnet is transformed into sodium hydrate alumina silicate at high temperature.
