Abstract

Abstract
In our study, five kinds of red mud samples from different aluminum factories were collected for sequencing batch leaching experiment to simulate the leaching behavior of rare metals of red mud in natural storage condition under different pH. The results showed that the leaching rates of La, Sc and Y decreased with the increase of pH, reached 45%, 82% and 64% respectively under extremely acidic conditions (2
