一、西德有色矿山的概况西德有色矿山为数不多,据目前资料,计有四个,分属于三个公司,即Grund铅锌矿和Rammelsberg铜铅锌矿,属于Preussag金属公司,Meggen铅锌硫铁矿属于Sachleben有限公司,Luderlich铅锌矿属于Altenberg矿业—冶金联合股份公司。五十年代西德全国进行开采的有色矿山大约20个,进入七十年代前期(1974年)只剩五个,到七十年代后期(1975年以后)又缩减到四个。但这四个矿山的产量却等于五十年代20
I. Overview of West German Non-ferrous Mines There are only a few non-ferrous mines in the West Germany. According to the current data, there are four subheadings belonging to three companies, namely Grund Lead-Zinc Mine and Rammelsberg Copper-Lead-Zinc Mine, belonging to Preussag Metals Company, Meggen Lead Zinc pyrite belongs to Sachleben GmbH, and Luderlich lead-zinc mine belongs to Altenberg Mining-Metallurgical Union AG. About 20 nonferrous mines were mined in the West Germany in the 1950s, leaving only five in the early seventies (1974) and four in the late seventies (after 1975). But the output of these four mines is equal to that of the 1950s
