蓝晶石族矿物包括蓝晶石、矽线石和红柱石,因其具有耐高温、抗腐蚀和煅燃后体积膨胀等特性而为人们所瞩目,成为钢铁工业的娇子,世界蓝晶石族矿产量的50%用于钢铁工业;由于近年钢铁工业的不断发展,对它的需求量更以每年10%的速度递增.我国的蓝晶石族矿各地均有发现,其中河北、辽宁、河南、新疆、山西、内蒙、广东、浙江、陕西等省 The kyanite minerals, including kyanite, sillimanite and andalusite, are attracting the attention of many people due to their high temperature resistance, corrosion resistance and volume expansion after calcined combustion. They have become the cradles of the steel industry, the world’s kyanite Due to the continuous development of the iron and steel industry in recent years, the demand for it has increased by 10% annually, and more than 50% of the mineral output has been found in all the places in China, including Hebei, Liaoning and Henan , Xinjiang, Shanxi, Inner Mongolia, Guangdong, Zhejiang, Shaanxi and other provinces
