摘要
研究了铝土矿渣与硫酸反应动力学,试验结果表明:铝土矿矿渣与硫酸反应受温度影响较大,浸出过程符合化学控制为主的收缩未反应芯模型;反应动力学方程为:1-(1-x)13=kt,k=216 exp[-33900RT]。
Kinetic study of the leaching of powered bauxite residue in sulfuric acid solution has been investigated. Leaching reaction is affected by reaction temperature and applicable to the chemical reaction according to shrinking core model. The reaction kinetics is 1-(1-x)^1/3=kt,k=216exp[-33900/RT]
