Design of an Orthogonal Test for Sulfuric Acid Soaking of Chrysotile

DUAN Tao1,PENG Tong-jiang1,LIUKun2(1.Southwest University of Science and Technology,Mianyang,Sichuan,China;2.Central South University,Changsha,Hunan,China)  
The influence factors of sulfuric acid soaking for treating chrysotile was investigated by means of orthogo-nal test.The results obtained showed thatthe following four factors have differentinfluences on sulfuric acid soakingof chrysotile :reaction temperature,reaction time,H2SO4concentration and liquid-solid ratio.The optimal techno-logical conditions were as follows:H2SO4concentration is 40%,reaction temperature is 100℃,reaction time is 4hand the ratio of liquid-solid is 8.
