霞石正长岩是一种熔点低,助熔性能强的碱性岩石,随着科学技术不断发展,综合利用能力的提高,霞石正长岩在国外早已成为玻璃、陶瓷、颜料增光剂、填料和铝工业原料。国内经我们几年来的调研,我国霞石正长岩的资源还是比较丰富,主要分布在辽宁、河北、山西、安徽、湖北、广东、云南和四川,其中目前最大的是四川会理霞石正长岩体。近几年来,国家建材局地质研究所对四川会理霞石正长岩体取样进行了选矿工艺及其应用研究,通过试验研究:该矿经过物理选矿方法可以获得理想的霞石正长岩精矿。霞石正长岩
Nepheline syenite is a kind of alkaline rocks with low melting point and strong fluxing ability. With the continuous development of science and technology and the improvement of comprehensive utilization ability, nepheline syenite has already become a glass, ceramic, Filler and aluminum industrial raw materials. According to our research over the past few years, our country nepheline syenite is still rich in resources, mainly distributed in Liaoning, Hebei, Shanxi, Anhui, Hubei, Guangdong, Yunnan and Sichuan, of which the largest is currently Sichuan Hui Li Xia Shi is Long rock body. In recent years, the National Bureau of Geology and Building Materials Bureau of Geological Exploration Institute of Sichuan will be Xia Shi Shengtan rock samples beneficiation process and its application, through experimental study: the ore after the physical beneficiation method can obtain the ideal nepheline syenite fine mine. Nepheline syenite
