Research output: Chapter in Book/Report/Conference proceedingChapter


In this study, the dissolution kinetics of silicon from sintering red mud in pure water was investigated. Experimental factors such as particle size and stirring speeds were studied to test their effect on the extraction fraction of silicon from red mud. It was found that the silicon extraction increases with stirring speed and decreasing in the particle size of red mud. Based on the experimental results, the Noyes-Whitney equation was adopted to describe and explain the dissolution behavior of the red mud in pure water, and the experimental data fit the model quite well in the whole process of dissolution.
