由于含铜砂岩一般品位较高,矿石露头松软,氧化矿居多,利用土法、小型生产可以直接迅速的炼出铜,故在我国当前铜的生产中是有很大实际意义的铜矿类型之一。如云南牟定、永胜,四川滎经、会理,湖北巴东,及宁夏隆德等地的著名土法炼铜厂,都是大量开采含铜砂岩矿石直接冶炼的。在世界铜矿资源中,含铜砂岩也占重要的地位(据有关资料1951年统计占全世界铜储量28％;1955年统计占全世界铜产量20～23％)。产状变化小、品位高、分布规模大、储量多是许多含铜砂岩矿床的共同特点。因此很多地质学家,尤其是苏联地质学
Due to the generally high grade of copper-bearing sandstones, loose ore outcrops, and a large number of oxidized mines, copper can be directly and rapidly extracted using the soil method and small-scale production. Therefore, it is of great practical significance in the production of copper in our country one. Such as Yunnan Mouding, Yongsheng, Sichuan Sujing, Huili, Hubei Badong, and Ningxia Lund and other places of the famous indigenous copper smelting, copper mining is a large number of ore direct smelting of sandstone. Among the world’s copper resources, copper-bearing sandstone also occupies an important position (according to relevant statistics, 1951 statistics accounted for 28% of the world’s copper reserves; in 1955, it accounted for 20 to 23% of the world’s copper production). Small changes in output, high grade, large-scale distribution, reserves are many common features of copper-bearing sandstone deposits. Therefore, many geologists, especially the Soviet geology
