随着建筑材料社会需求量的激增,目前对一些白度稍低,Al_2O_3含量中等,可塑指数较高的高岭土矿引起了人们的重视。宁芜中生代火山岩盆地北段(江苏部分——下同),此类高岭土矿点分布普遍。其中规模较大、出露标高较高、易采易选者已被地方开采利用,并已获得较好的经济效益和社会效益。如祖堂山、狮子山的高岭土分别由江 With the rapid growth of the demand for building materials in society, some kaolin mines with lower whiteness, medium Al_2O_3 content and higher plasticity index have attracted people’s attention. Ning Wuzuo Mesozoic volcanic basin north section (Jiangsu part - the same below), the distribution of such kaolin mine is widespread. Among them, large-scale and high exposed elevations, easy-to-use and easy-to-choose have been exploited by localities and have obtained good economic and social benefits. Such as Zu Tang Shan, Lion Rock kaolin by the river
