一、含铜砂岩矿床的重要性含铜砂岩矿床,是目前世界上仅次于斑岩铜矿的第二个最重要的铜的工业来源。据外刊报导,1970年初资本主义世界铜的总储量有35％产于含铜砂岩矿床内。我国含铜砂岩分布很广,许多省(区)均有发现,而以西南各省矿床最多,探明储量不断增加,成为我国重要铜矿类型之一。
First, the importance of copper-bearing sandstone deposits Copper-bearing sandstone deposits, is the world’s second only to the porphyry copper mine, the second most important industrial source of copper. According to foreign press reports, in the early 1970s, 35% of the total reserves of copper in the capitalist world were produced in copper-bearing sandstone deposits. Copper-bearing sandstones in our country are widely distributed, and many provinces (regions) have been discovered. However, most of the deposits in the southwestern provinces have increased in proven reserves and become one of the important copper deposits in China.
