Purification Experiment Study of Carbonous Hard Lei Shaomin;Cui Guozhi(Institute of Non-Metallic Mines, WUT)This paper studied the mineral property of carbonous hard kaolin in west of Hubei. Researched purify technology and main factors effecting quality of kaolin. Indicated developing the source should be mainly on calcined kaolin. Pointed out the direction and ways of developing the source in west of Hubei.:hard baolin;ultra-fine comminution;purifing iron and carbon; calcine
