斑岩铜矿,又称细脉浸染状铜矿,是重要的铜矿工业类型之一。目前,此类型铜矿在资本主义国家约占总储量的65-70％,我国为24％。该类型矿床多呈大型网脉状产出,具有规模大、品位低、易开采的特点,亦经常出现矽卡岩型与斑岩型矿共生的现象。矿石储量,单个矿床往往超过一千万吨,常达几亿——几十亿吨(如美国、加拿大、智利、秘鲁和墨西哥26个著名的矿床中,3-5亿吨的有9个、5-10亿吨的有4个、10-20亿吨的有2个);金属储量常达几十万一几百万吨(如我国江西德兴、西藏玉龙等铜矿达××万-×××万吨)。但其中大部分为贫矿,少数为富矿,一般品位较低,大多矿床原生矿石含Cu在0.4％以下,少数可达0.8％或略高,次生富集带可达1-2％。矿石还伴含有Mo、W、Bi、Co、Pb、Zn、Ag、Au和稀有元素等有用组分。
Porphyry copper, also known as fine vein disseminated copper, is one of the important copper industry type. At present, this type of copper mine accounts for about 65-70% of the total reserves in capitalist countries and 24% in our country. This type of deposit is mostly large net veins, with large scale, low grade, easy to exploit the characteristics of skarn and porphyry ore are often the phenomenon of symbiotic. Ore reserves, often over 10 million tons of single deposits, often hundreds of millions - billions of tons (such as the United States, Canada, Chile, Peru and Mexico, 26 well-known deposits, 3-5 tons of 9, 4 to 5-10 billion tons and 2 to 10-2 billion tons); metal reserves are often in the tens of thousands to millions of tons (eg, Dexing, Jiangxi and Yulong in Tibet reach XX million - × × × tons). However, most of them are lean mines and a few are rich in ore, with generally low grade. Most of the primary ore deposits in most deposits contain less than 0.4% Cu, a few up to 0.8% or slightly higher, and secondary enrichment zones up to 1-2%. The ore also contains useful components such as Mo, W, Bi, Co, Pb, Zn, Ag, Au and rare elements.
