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 are-a, 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.%陕西省红柱石矿开发已有十多年的历史,有一套成熟的加工处理红柱石矿的方法和经验.矿石加工方法简单,也无须添加任何药剂,生产成本低,对周围环境影响小,矿山的经济效益和社会效益良好.在陕西宝鸡地区的眉县、太白境内分布有大量的花岗岩和花岗闪长岩,围绕岩体分布有大量的泥质板岩、千枚岩,成矿地质条件得天独厚,具有寻找、开发红柱石矿的优势.
