1.云母:我国探明的资源均为块云母,截至1988年底,列入矿产储量表的产地共140处,集中分布于新疆、四川及内蒙三省(区)。我国碎云母资源前景很好,地质勘查正在开展,河北灵寿矿区已由地方开采。块云母的现有生产能力已能满足需要,现有储量已可保证本世纪至下世纪20年代的需要。预测到2000年我国碎云母的年需求量将是1988年产量的2.5倍,建议加强碎云母矿的地质勘查工作。2.沸石:我国沸石矿资源丰富,居世界前列。截至1988年底,上储量表的矿产地25处,主要分布在我国东部,以中等品位的斜发沸石和丝光沸石应用较为广泛。当前及
1. Mica: All the proven resources in the country are block micas. As of the end of 1988, 140 sites of mineral reserves were included in the distribution, concentrated in three provinces (regions) of Xinjiang, Sichuan and Inner Mongolia. The prospect of broken mica resources in China is very good, geological prospecting is under way and the Lingshou mining area in Hebei Province has been exploited by local authorities. The existing production capacity of block mica has been able to meet the need, the existing reserves have been able to ensure that this century to the next century the needs of the 1920s. It is estimated that the annual demand of broken mica in China in 2000 will be 2.5 times that of 1988, and it is suggested to strengthen the geological prospecting of broken mica ore. 2. Zeolite: China’s zeolite rich mineral resources, the world’s forefront. By the end of 1988, there were 25 places of mineral deposits in the Upper Stockpile, mainly distributed in the eastern part of our country. The application of clinoptilolite and mordenite with medium grade is more extensive. Current and
