一、世界矿产资源的现状世界矿产资源的分布极不均衡,在40个矿种中,有13种矿产(锰、铬、钴、钼、钒、铂族金属、锂、铌、钽、锆、稀土、钾盐、天然碱)3/4以上的储量集中在3个国家(美国、俄罗斯、中国),有23种矿产(除以上13种外加上钨、菱镁矿、钛铁矿、金红石、锡、锑、磷、硼、金刚石、重晶石)3/4以上的储量集中在5个国家。40种主要矿产中,储量排在前3位的国家,其储量占世界总储量的比例最低为30.7%,最高为99.5%,前5
First, the status of the world’s mineral resources The world mineral resources are extremely uneven distribution of minerals in the 40, there are 13 kinds of minerals (manganese, chromium, cobalt, molybdenum, vanadium, platinum group metals, lithium, niobium, tantalum, Rare earth, potash, trona) 3/4 The reserves are concentrated in 3 countries (USA, Russia, China) with 23 minerals (excluding the 13 above plus tungsten, magnesite, ilmenite, rutile, Tin, antimony, phosphorus, boron, diamond, barite) 3/4 The reserves are concentrated in five countries. Of the 40 major minerals, the countries with the highest reserves in the world’s top 3 reserves account for the lowest percentage of total world reserves of 30.7% and the highest percentage of 99.5%
