The calcium bentonite was converted into sodium bentonite with sodium chloride as the conversion agent by suspension method.With the application of the uniform design experiment method, the best prepared conditions were selected, and cation exchange capacity, dilation volume, colloid valence, blue absorption power were determined.It was showed that the sodium bentonite was greater than calcium bentonite, and with ore concentration of 16%, sodium chloride dose of 6%, reaction temperature of 65 ℃, reaction time of 90 min, sodium modification effect was best.The cation exchange capacity of 0.992 mmol · g-1 , dilation volume of 19.7 mL · g-1 , colloid valence of 5.98 mL · g-1 , blue absorption power of 0.387 mmol· g-1 were achieved.They approached the standard of first-class product.
