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.
