Abstract: Fujian province has abundant and widely distributed fluorite mineral resources, which are divided into three fluorite mineralization sub zones and eight fluorite mineralization prospect areas. Mainly distributed in the cities and counties under the jurisdiction of Nanping city and Sanming city, it is mainly produced in the Chong’An-Anyuan ne-trending deep and large fault zone, the Pucheng-Songkou, Jangle-Hua’an, Taining-Longyan north-south trending fault zone, and the Guangze-Wuping north north east trending fault zone, in recent years, new techniques and new methods have been applied to find ore deposits with good results.
Keywords: fluorite; resources; fault zone; granite
萤石是一种熔点较低的矿物,熔点在1 270~1 350 ℃,主要化学成分为氟化钙(CaF2),是冶金行业不可缺少的熔剂,也是氟化工行业的资源保障,主要应用于新能源(风能、太阳能)、新能源汽车(锂电池、密封件)、核工业(铀加工)、新一代信息技术(半导体、平板显示)等行业[1-2],对国家经济安全和战略性新兴产业具有重要作用。(剩余3346字)
