Ten years passed since andalusite exploitation started in Shaanxi province.There has been a set of established methods and experiences accumulated for processing andalusite ore.The ore processing methods are simple without adding any medicament and production cost of the methods is low with minimum influence on the environment.Therefore,economic and social benefits have been received from all the andalusite mines.There are a great deal of granite and granodiorite spreading in Meixian and Taibai county in Baoji area,Shaanxi province.Intrusive rocks are surrounded by plentiful argillite and phyllite.So these areas have a favourable mineralised conditions and the advantages could be taken for searching and developing andalusite deposits.
