MAJOR DIAMOND PRODUCTORS IN 21st CENTURY
-
摘要: 在21世纪,世界钻石主要采自非洲、澳大利亚、俄罗斯和加拿大。其中非洲是最主要的产地,主要的产钻国是博茨瓦纳、南非和刚果民主共和国(原称扎伊尔),此外安哥拉和纳米比亚也产少量钻石。比较重要的矿山有博茨瓦纳的Jwaneng矿和Venetia矿以及南非的Premier矿、Finsch矿和Orapa矿。这些矿山的预计开采年限还有20多年。澳大利亚的钻石矿床主要集中在西澳大利亚地区,其中最主要的是Argyle矿。俄罗斯的钻石矿床多分布在西伯利亚台地和俄罗斯台地,随着新的勘探方法的应用,在俄罗斯还可能发现新的钻石矿床。加拿大是一个新的钻石产地,钻石矿床主要集中在西北区,目前最重要的是Ekati矿。尽管加拿大目前的钻石产量不高,但在不久的将来,随着科学技术的发展,其产量会有所提高,从而成为一个主要的钻石产地。Abstract: In the 21st century, several major diamond producers are Africa, Australia, Russia and Canada. Among them Africa is the most important producer, including Botswana, South Africa, DR Congo (formerly Zaire), Angola and Namibia. The diamonds may be mainly mined from several important mines, such as Jwaneng mine and Orapa mine in Botstana, and Premier mine, Finsch mine and Venetia mine in South Africa. These mines are expected to produce for more than 20 years. Diamond deposits in Australia are concentrated in the West Australia, and the most important is the Argyle mine. Diamond deposits in Russia are mainly distributed on the Siberian Craton and Russian Craton. Some new deposits may be found due to the application of new prospecting methods. Canada is a new diamond producer, and diamond deposits are concentrated in the Northwest Territories, among which the Ekati mine is the most important now. At present, diamond production from Canada cannot match that from any other major producer, but it will become an important source, with the development in science and technology.
