我国金刚石资源主要分布在山东省的蒙阴、郯城,湖南省的常德、桃源、黔阳,辽宁省的复县等地。国产天然金刚石中,主要来源于三个金刚石矿,其中常德、桃源、黔阳、郯城金刚石矿属砂矿,产品质量较好;蒙阴金刚石矿属金伯利岩型原生矿。砂矿金刚石产量每年约在1、2万克拉左右,原生矿金刚石则约在5至7万克拉左右。金刚石广泛用于冶金、机械、石油、煤炭、仪器仪表、电子工业及空间技术方面,为国民经济振兴和科技发展起了重要的作用。
China’s diamond resources are mainly distributed in Mengyin, Tancheng in Shandong Province, Changde, Hunan Province, Taoyuan, Guizhou, Guizhou Province, Liaoning Province, Fu County and other places. Among the domestic natural diamonds, they are mainly derived from three diamond mines, of which the diamond mines in Changde, Taoyuan, Qianyang and Tancheng are good, and the products are of good quality. The Mengyin diamond mine is a kimberlite primary ore. The output of placer diamonds is about 12,000 karats per year, while that of primary diamonds is about 5 to 70,000 karats. Diamond is widely used in metallurgy, machinery, petroleum, coal, instrumentation, electronics and space technology and plays an important role in rejuvenating the economy and developing science and technology.
