design (BBD) was used in the optimization of the main operating parameters. The results reveal that flotation indexes are effectively improved after coagulation treatment by polyaluminum ferric chloride... treatment. Key words: backwater treatment; bauxite flotation; polyaluminum ferric chloride; Box-Behnken design 1 Introduction Ore grade decreases because of the sharp and increasing demand of bauxite [1......
