Abstract：By controlling single experimental conditions,barite was prepared through hydrophobic agglomeration with sodium oleate.The relationships among the after-modified barite and the amount of sodium oleate,modification temperature,modification time,slurry concentration were expounded.The results show that the optimal modification conditions are as follow:the amount of sodium oleate 1.0％,modification time 15 min,modified temperature 80 ℃C,the concentration of slurry 30％.The wetting contact angle of after-modified barite is 128 °,the surface of barite is changed into hydrophobic.
