某些矿床由于受其成因影响,矿石中往往伴生有多种国家需缺的贵重金属和稀有分散元素。四川攀西地区的钒钛磁铁矿,含铂、钯的铜镍矿,以及伴有大量银、硒的砂砾岩型铜矿,就是属于这些类型有代表性的矿床。 矿山保护,综合利用很重要。自然界不同地质时期多种地质因素和矿床的多成因作用形成的不同类型的共生矿,是矿床找矿勘探的主要对象,是开发矿业的重要物质基础。实践证明,做好矿产综合评价、综合勘探,促进矿产资源的综合利用,即能提高矿床的利用价值,实现一矿变多矿,又可促使表外矿转化为表内矿,进而探明更多的可供生产
Due to the genesis of some deposits, the ore often has associated precious metals and rare dispersed elements that many countries lack. Vanadium-titanium magnetite in Panxi, Sichuan Province, copper-nickel ore containing platinum and palladium, and conglomerate-type copper deposits with a large amount of silver and selenium belong to the representative deposits of these types. Mine protection, comprehensive utilization is very important. Different types of symbiotic ore formed by multiple geologic factors in different geological periods and multi-genesis of ore deposits are the main targets of deposit prospecting and exploration and an important material basis for the development of mining. Practice has proved that comprehensive mineral evaluation, comprehensive exploration, and promote the comprehensive utilization of mineral resources, that can increase the utilization value of the deposit to achieve more mine ore, but also to promote the table outside the mine into table ore, and then identify more More for production
