本文就世界钽资源开发利用、国际市场钽原料价格变化,钽的生产和消费,钽产品结构变化等方面进行分析和预测,预示出今后十年国外钽工业将有一个稳步发展的趋势。 一、世界钽资源开发利用情况 目前,世界钽的资源主要来自钽铁矿、铌铁矿和伴生在锡矿中的钽矿物。根据日本技术院调查所的报告和其他有关资料的统计,世界钽(以Ta_2O_5计)的总储量(包括潜在储量,未包括中国)为25.5万吨,储量较大的国家主要有苏联和扎伊尔(见表1)。
This article analyzes and forecasts the development and utilization of tantalum resources in the world, the price changes of tantalum raw materials in the international market, the production and consumption of tantalum, and the structural changes of tantalum products, which indicates that the tantalum industry in foreign countries will have a steady development trend in the next 10 years. I. Development and Utilization of Tantalum Resources in the World Currently, the world’s resources for tantalum are mainly derived from tantalite, niobium iron and tantalum minerals associated with tin mines. According to the report by the Japan Institute of Technology and other relevant statistics, the total reserves of tantalum in the world (based on Ta 2 O 5) (including potential reserves excluding China) are 255,000 tons. The countries with large reserves mainly include the Soviet Union and Zaire Seoul (see Table 1).
