我国银矿资源特点
The characteristics of China's silver mineral resources
产地分布广泛，储量相对集中
Origin is widely distributed, the reserves are relatively concentrated
全国已探明有储量的产地有569处，分布在27个省、市、自治区。储量在万t以上的省有江西、云南、广东；储量在10000～5000t的省（区）有内蒙古、广西、湖北、甘肃。这7个省（区）的储量占了全国总保有储量的60.7%。其余20个省、市、自治区的储量只占全国总储量的39.3%。
The country has proven reserves of origin 569, distributed in 27 provinces, city, autonomous region. Reserves in million T above provinces include Jiangxi, Yunnan, Guangdong; reserves in 10000 ~ 5000t of the province (area) with Inner Mongolia, Guangxi, Hubei, Gansu. These 7 provinces (area) reserves accounted for 60.7% of the total reserves. The remaining 20 provinces, city, autonomous region reserves accounted for only 39.3% of the total reserves.
贫矿多，富矿少，伴生银资源丰富，产地多，但贫矿多，富矿少
More low-grade ores, ore less, associated silver resources are rich, origin, but the more low-grade ores, ore less
中国伴生银资源丰富，1995年，保有储量66146t，占当年银总保有储量的58%，尚有一部分矿区未进行银的分析或未计算储量，伴生银矿储量实际上应更多些。全国除宁夏外，其他各省、市、自治区都有伴生银产地。伴生银矿储量和产地以江西、湖北、广东、广西和云南为最多。但是中国伴生银矿富矿少，贫矿多，银品位大于50g/t的富伴生银矿只占伴生银矿储量的1/4左右，而银品位小于50g/t的贫伴生银矿储量却占伴生银矿总储量的3/4。
Chinese associated silver resources are rich, in 1995, to maintain reserves of 66146t, accounting for the total reserves of 58% silver, there is a part of the mining area of analysis of silver or no calculation of reserves, the associated silver reserves should actually be more. The country except Ningxia, other provinces, city, autonomous region have associated silver origin. The associated silver reserves and origin to Jiangxi, Hubei, Guangdong, Guangxi and Yunnan as the most populous. But Chinese associated Ag ore less, more low-grade ores, silver grade greater than 50g/t rich associated silver deposit associated silver reserves account for only about 1/4, while the silver grade less than 50g/t poor associated silver reserves but accounts for the total reserves of associated Ag 3/4.
大、中型产地少，占有的储量多；大、中型产地少，占有的储量多；小型产地多，占有的储量少
Large, medium low origin, occupies plenty of big, medium-sized; low origin, possession of the reserves; small origin, occupies less reserves
据1992年的资料分析，中国以银为主要开采对象的银矿，大型产地12处，中型产地40处，大、中型产地占有的储量占该类银矿储量的95%；小型产地29处，占有的储量只占5%左右。伴生银矿大型产地14处，中型产地73处，大、中型产地占有的伴生银矿储量占伴生银矿总储量的79%，而小型产地有271处，占有的伴生银矿储量只占伴生银矿总储量的21%。
According to the analysis of the data of 1992, China with silver as a main exploration object silver, large producing 12, medium-sized origin 40, big, medium-sized origin of possession of the reserves of this kind of silver reserves of 95%; small origin 29, holds reserves accounted for only about 5%. Associated silver deposit large producing 14, medium-sized origin 73, big, medium-sized origin of possession of the associated silver deposit associated silver reserves accounted for 79% of total reserves, while the small origin 271, possession of the associated silver reserves only account for 21% of the total reserves of associated silver deposit.
银多与铅锌共生或伴生
Silver lead zinc and the symbiotic or associated
中国共生银矿以银铅锌矿为多，其保有储量占银矿储量的64.3%
China symbiotic silver to silver lead zinc ore is much, its reserves accounted for silver reserves 64.3%
银铅锌矿
Silver lead zinc mine
。伴生银矿主要产在铅锌矿（占伴生银矿储量的44%）和铜矿（占伴生银矿储量的31.6%）中。与银共生或伴生的除了铅锌和铜外，还有锡矿、金矿，以及多金属矿等。
. Associated silver deposit are mainly produced in lead zinc mine (associated silver reserves accounted for 44%) and copper (accounting for 31.6% of the associated silver reserves). And silver symbiotic or associated except lead zinc and copper, and tin, gold, and multi metal ore etc..
一种银矿。化学成分为Ag3AsS3、晶体属三方晶系的硫盐矿物。又名硫砷银矿。英文名来源于法国化学家J.－L.普鲁斯特(J.-L.Proust)的姓氏。
A silver. The chemical composition for the sulfosalt minerals Ag3AsS3, crystal is the three party system. Also known as proustite. The English name comes from the French chemist J.L. Proust (J.-L.Proust) name.
淡红银矿呈鲜红色，条痕也是鲜红色，在光线下颜色变暗。半透明到不透明，金刚光泽到半金属光泽。其表面因易氧化而常被暗黑色的薄膜所覆盖，粉末呈砖红色。摩氏硬度2～2.5，比重5.57～5.64，清楚菱面体解理，断口贝壳状至参差状。溶于硝酸，易熔。晶体的两端不对称，呈异极形的短柱状；通常呈粒状和块状产出。晶体柱状、菱面体和偏三角面体。也以块状或致密状集合体产出。
Proustite was bright red streak is bright red, in the light dark. Translucent to opaque, adamantine luster to the semi metallic luster. The surface because of easy oxidation film is often dark covered, powder are brick red. Mohs hardness of 2 to 2.5, the proportion of 5.57 to 5.64, clear the rhombohedral cleavage, fracture conchoidal to uneven. Soluble in nitric acid, fusible. Both ends of the asymmetric crystal, was hetero shaped short column; usually in the form of granular and massive output. Crystal column, rhombohedral and scalenohedron. Also to block or dense aggregations.
淡红银矿是热液成因的矿物。通常都与其他银矿物一起产出，作为银矿石利用。与多种矿物伴生于热液矿脉，如黝铜矿和砷黝铜矿，以及一些硫化物，如方铅矿，还有石英。中国辽宁、江西、青海、广东等省的铅锌银矿床中均有淡红银矿。美观的大晶体发现于智利的查纳西约。墨西哥、玻利维亚、德国有著名产地。淡红银矿除作为提炼银的矿物原料外，其单晶体可用作激光材料。
Proustite is hydrothermal mineral. Usually with other silver minerals with output, as silver ore utilization. And a variety of mineral associated hydrothermal veins, such as tetrahedrite and tennantite, and some sulfides such as galena, and quartz. Lead zinc silver deposit, Liaoning, Jiangxi, Qinghai and Guangdong province of China in proustite. The appearance of the large crystals found in Chile Naxiyue check. Mexico, Bolivia, Germany has a place famous for. Proustite except as a source of silver mineral raw material, and its single crystal can be used as laser material.
