摘要: 通过石煤焙烧渣酸浸试验,考查了在不同硫酸浓度、浸出温度、浸出时间、搅拌速度和液固比条件下,铝钒的浸出行为。结果表明,铝浸出率与钒浸出率呈良好的线性关系,各线性回归方程相关系数R2均大于0.96,铝钒浸出行为具有一致性。  

关键词: 石煤, 酸浸, 相关性

Abstract: Leaching behaviors of Al and V under different H2SO4 concentration,leaching temperature,leaching time,stirring speed and liquid-solid ratio were investigated through leaching experiments.The experimental result demonstrated the relationship between Al leaching behavior and V leaching behavior is linear and all Adj.R2 of linear regression equations is more than 0.96.Al leaching behavior is consistent with V leaching behavior.
