一、钨 1.钨的资源 钨是我国具有战略优势的资源,其储量居世界首位,占世界总资源的40％左右。我国钨矿区有250多个,分布比较集中,江西、湖南两省的储量占全国储量的50％以上。在保有黑钨工业储量的59.19万吨中,不可开采量约为23％,按年精矿产量5.23万吨计,黑钨矿可供开采13～14年。到2010年我国黑钨工业储量将耗尽,目前缺乏可供接替用的优质黑钨矿基地。 我国白钨资源与国外一样,在钨资源中占重要地位,占我国钨保有工业储量的73.2％,但矿石品位>0.5％以上,只有11.1万吨,占6.5％;矿石品位
I. Tungsten 1. Resources of Tungsten Tungsten is a resource of strategic importance in our country and its reserves rank first in the world, accounting for about 40% of the total resources in the world. There are over 250 tungsten mines in our country, with a relatively concentrated distribution. Reserves of Jiangxi and Hunan provinces account for over 50% of the national reserves. Among the 591,900 tons of black tungsten industrial reserves retained, the non-exploitable amount is about 23%. According to the annual output of 52,300 tons of concentrate, the wolframite can be mined for 13 to 14 years. By 2010 China’s tungsten industry reserves will run out, the current lack of alternative high-quality wolfram mine base. China’s white tungsten resources, like foreign countries, occupy an important position in tungsten resources, accounting for 73.2% of the total tungsten reserves in China. However, the ore grade is above 0.5%, with only 111,000 tons, accounting for 6.5%
