智利和秘鲁是世界上主要的铜资源国和产铜国.两国铜矿资源绝大部分来自斑岩铜矿.智利现有铜储量(金属量,下同)1.5亿吨,名列世界第一.1978年产铜104万吨,仅次手美国(135万吨)、苏联(110万吨).智利斑岩铜矿带从该国中部的特尼恩特铜矿到最北部的莫恰铜矿长两千多公里,带内有几十个大小不等的铜矿床.其中储量在100万吨以上的矿床不下十几个.特别是北部的丘基卡马塔和中部的特尼恩特铜矿,为世界上最大的斑岩铜矿床.秘鲁现有铜储量2720万吨,居世界第七位.1978年产铜35万吨,位于美、苏、智、加、赞、扎之后.全秘鲁大致可以分北部、中部及南部三个铜矿带,其中以南部斑岩铜矿带最重要.该带从最南部的托克帕拉矿床往北西延伸长约千余公里,现有斑岩铜矿床
Chile and Peru are the world’s major sources of copper and copper-producing countries. Most of the copper resources in the two countries come from porphyry copper. Chile has 150 million tons of copper reserves (the same below) 1. In 1978, 1.04 million tons of copper was produced, only secondarily to the United States (1.35 million tons) and the Soviet Union (1.1 million tons). The Chilean porphyry copper belt runs from the Teiente copper mine in the central part of the country to the northernmost part of Moccia More than two thousand kilometers of copper mine, with dozens of copper deposits of varying sizes, of which more than a dozen reserves of more than 1 million tons of deposits, especially in the north of Chu Ji Kamata and central Teney Ente copper mine is the largest porphyry copper deposit in the world, Peru has 27.2 million tons of copper reserves, ranking the seventh in the world. In 1978, it produced 350,000 tons of copper in the United States, the Soviet Union, Chile, Canada, Canada, After all, Peru can be divided into three northern, central and southern copper belt, of which the southern porphyry copper belt is most important.The belt from the south of the Topkapala deposit extends northwest about 1000 kilometers, Existing porphyry copper deposit
