Modifications of red mud for activating available silicon (Si) by phosphates were carried on in this paper. And then the modified materials used to stabilize Cd an ore soil. Results indicated that efficiently increase content Si mud. In stabilization, exchange was decreased 90.97% when using 5% potassium dihydrogen phosphate mud, which better than raw re as decrease 77.08%. rice pot soil, increases residue positively correlated with (P<0.05, R=0.9965). Contents root increased 53.87% while it 24.17% adding 3%
