锡矿

Tin

截至1999 年底，我国共有锡矿产地298 处，分布于全国15 个省、自治区，但锡保有储量主要集中在广西、云南、广东、湖南、内蒙古、江西。以上6 省（区） 保有储量占全国总保有储量的97．6 ％。我国锡矿资源重要远景区有：西南三江南段和西北天山等地区。

By the end of 1999, China had tin producing 298, distributed in 15 provinces, autonomous regions, but tin reserves are mainly concentrated in Guangxi, Yunnan, Guangdong, Hunan, Inner Mongolia, Jiangxi. More than 6 provinces (area) to maintain reserves accounted for 97.6% of the total reserves. The important prospecting ore resources in China: Southwest and northwest Sanjiang South Tianshan area.

我国锡矿有如下特点：

China's tin has the characteristics as follows:

一是以原生锡矿为主，砂锡矿居次要地位。在全国总储量中，原生锚矿约占90 ％，砂锡矿仅占10 ％。原生矿物中，锡石硫化物型多金属矿床的储量约占总储量80 ％。

One is the primary tin, tin ore secondary importance. In the country's total reserves, accounting for about 90% of primary anchor ore, tin ore accounted for only 10%. Primary mineral, cassiterite sulfide type polymetallic deposit reserves total reserves 80%.

二是共伴生组分多。我国锡矿作为单一矿产形式出现的只占12 ％，作为主矿产的锡矿占全国总储量的6696 ，作为共伴生组分的锡矿占全国总储量的22 ％。共生及伴生的矿产有铜、铅、锌、钨、锑、钼、铋、银、铌、钽、铍、铟、镓、锗、镉， 以及铁、硫、砷、萤石等。

A total of two is associated components. China tin as a single mineral form only accounted for 12%, as the main mineral of tin ore accounted for 6696 of the national total reserves, as the associated component tin ore accounted for 22% of the national total reserves. Paragenetic and associated minerals are copper, lead, zinc, tungsten, antimony, bismuth, molybdenum, niobium, tantalum, silver, indium, gallium, germanium, beryllium, cadmium, iron, sulfur, arsenic, and fluorite etc..

三是大、中型矿床多。我国锡矿大、中型矿床多，尤以云南个旧和广西大厂最为著名，是世界级的多金属超大型锡矿区。

Three large, medium-sized deposits. China's Tin big, medium-sized deposits, especially in Yunnan Gejiu and Dachang in Guangxi is the most famous, is a multi metal world class super large tin deposit.
