铜矿

Copper mine

截至1999 年底，全国探明铜矿产地918 处，富铜矿（品位＞1 ％） 储量占所有储量的35．2 ％。中国铜资源分布比较分散，全国28 个省（区） 都有铜矿的分布。铜矿储量较多的省（区） 分别是江西、西藏、云南、甘肃、安徽、内蒙古、山西、黑龙江、湖北、新疆。

By the end of 1999, the national proven copper producing 918, rich copper (grade > 1%) reserves accounted for 35.2% of all the reserves. Scattered distribution China copper resources, the country's 28 provinces (regions) have copper mine. Copper reserves of more provinces (area) are Jiangxi, Tibet, Yunnan, Gansu, Anhui, Inner Mongolia, Shanxi, Heilongjiang, Hubei, Xinjiang.

我国铜矿资源有如下特点：

Copper resources in China have the following characteristics:

一是中小型矿床多，大型、超大型矿床少。铜矿储量大于250 万吨以上的矿床仅有江西德兴铜矿、西藏玉龙铜矿、金川铜镍矿、东川铜矿等。在探明的矿产地中，大型、超大型仅占3 ％，中型占9 ％，小型占88 ％。

One is the small and medium-sized deposits, large, super large mineral deposits less. Copper reserves of more than 2500000 tons of ore of Dexing copper mine, only Jiangxi Tibet ERON copper mine, Jinchuan copper nickel mine, Dongchuan copper mine. In the mines, large-scale, ultra large scale only accounted for 3%, and accounted for 9%, small 88%.

二是贫矿多，富矿少。中国铜矿平均品位为0．87 ％，品位＞1 ％ 的铜储量占全国铜矿总储量的35．2 ％。在大型铜矿中，品位＞1 ％的铜储量仅占13．2 ％。

The two is more low-grade ores, ore less. Chinese copper average grade 0.87%, grade, 1% copper reserves accounted for 35.2% of the total reserves of the national copper. In a large copper, grade > 1% copper reserves accounted for only 13.2%.

三是共伴生矿多， 单一矿少。在900 多个矿床中单一矿仅占27．1 ％， 综合矿占72．9 ％，具有较大综合利用价值。在斑岩型铜矿床中，多数矿床共生钼，伴生金、银、铟、锗、铊、铼、镉、硒以及铂族元素；岩浆型铜镍硫化物矿床，铜镍共生，伴生钴、铂族、金、银、镓、锗、铊、硒、碲等；矽卡岩型铜及多金属矿床，铜、铁、铅、锌、钨等常共生在一个矿床中，并伴生钻、锡、钼、金、银、镓、锗、铼、镉、硒、碲等；海相火山岩型铜多金属矿床， 铜、铅、锌和黄铁矿常共生产出， 并伴生金、银、硒、镉、铟、铊、钼、钻等； 沉积岩中层状铜矿床常伴生铅、锌、钛、钒、镍、钻、锡、金、银、汞、镓、锗、镉、铊、铀、钍、硒等。

Three is a common associated minerals, the single ore less. In more than 900 single ore deposits accounted for only 27.1%, comprehensive ore accounted for 72.9%, with the comprehensive utilization of great value. In the porphyry copper deposit, most deposits associated molybdenum, associated with gold, silver, indium, germanium, selenium, cadmium, thallium, rhenium and platinum group elements; magmatic Cu Ni sulfide deposit, copper nickel symbiosis, associated cobalt, platinum, gold, silver, gallium, germanium, selenium, tellurium, thallium; skarn type copper and polymetallic deposit, copper, iron, lead, zinc, tungsten, often coexist in a deposit, and associated with drilling, tin, molybdenum, gold, silver, gallium, germanium, selenium, tellurium, cadmium, rhenium; marine volcano rock type copper polymetallic deposits, copper zinc, lead, and pyrite were produced, and the associated gold, silver, selenium, cadmium, thallium, indium, molybdenum, drilling; sedimentary rocks in the stratiform copper deposits are associated with lead, zinc, titanium, vanadium, nickel, tin, gold, diamond, silver, gallium, germanium, cadmium, mercury, thallium, uranium, thorium, selenium and so on.
