一、前言 我国是世界上主要产钨的国家,无论在资源上或产量上都占世界首位。就钨矿资源来说,1980年底统计数表明,现保有三氧化钨占世界总钨矿资源的56％。我国钨矿资源以黑钨矿为主,伴生组份多,主要有锡、钼,铋、铜、铅、锌、锑、金、银等有色金属和贵金属,以及锂、铍、铌、钽、钪、稀土、铀、钍等稀有金属。这么好的钨矿资源是我 I. Preface China is the world’s major tungsten producing country, both in terms of resources or output in the world. For tungsten resources, the statistics at the end of 1980 showed that tungsten trioxide now occupies 56% of the world’s total tungsten resources. China’s tungsten ore resources mainly include wolframite and associated components. The main sources of these resources include tin, molybdenum, bismuth, copper, lead, zinc, antimony, gold and silver, as well as nonferrous metals such as lithium, beryllium, niobium, tantalum, Scandium, rare earth, uranium, thorium and other rare metals.
